Greg, who was born and raised in Pasadena, California, was introduced to the world of numismatics by his uncle, Gene Calvert. One year, when he was about 11 years old, his uncle gave him a coin album for Christmas. Two years later, Greg attended his first coin club meeting with his uncle. F​rom these initial experiences Greg soon developed into a collector, but equally quickly to develop was his interest in the business and trading side of the rare coin market.
 
During his high school years, Greg learned that he was able to mak​e extra money buying and selling coins. His transition from a hobbyist to a dealer came naturally, especially since weekend trips to local coin shows provided Greg with enough money that he did not need to have another job while going to school. He eventually ended up selling coins to his high school principal as well as his friends.

After graduating from high school, Greg began attending college while also working for Nick Buzolich, Sr. and Nick Buzolich, Jr. at Quality Coin Exchange, a father-son wholesale partnership. The year was 1980, and Greg credits them with giving him his first formal education in the coin industry.

Greg next moved on to a coin buyer position with a retail operation in Newport Beach, California. During his nine-year tenure with the firm he helped bring in more than $120 million worth of coins. He started his own coin business in 1990.

Today, as CEO of Stack's Bowers Galleries and Amark, Greg manages an international collectibles network with affiliates headquartered on three continents.

Greg is a member of the Professional Numismatists Guild (PNG), a life member of the American Numismatic Association (ANA), and a member of the Industry Council for Tangible Assets (ICTA). He is married, loves spending time with his children and is a big fan of the California Angels and Los Angeles Lakers.

Always interested in coinage and history, Jeremy inherited the coin collecting gene from his maternal grandfather. He began in the hobby as many often do—seeking out U.S. type coins and reading the Red Book from cover to cover. While in college, he began working part-time in the brick-and-mortar coin shop that he had visited throughout his youth. There, he gained valuable experience from the “other side of the counter,” interacting with the public by selling to and buying from customers, as well as sorting and cataloging purchases and setting up at local and regional coin shows.
He continued his experience in the trade by spending the past 12 years working at numerous prestigious auction houses and firms, chiefly in charge of cataloging and presenting ancient and world coins from all areas, as well as researching exonumia (such as medals and tokens), communicating with customers regarding the evaluation and placement of their consignments, and serving as a representative on  bourse floors and at auctions.
He now brings this wealth of knowledge Stack’s Bowers Galleries, where he is a main contributor to the cataloging and presentation of ancient coins, world coins, and medals. He also conducts research for our popular “Coin of the Week” blog posts. He considers medals to be an unexplored treasure, representing a true “final frontier” of the hobby, and he enjoys shedding light upon this highly interesting niche aspect of numismatics.

Dennis Hengeveld grew up in the Netherlands and has been involved in numismatics since the age of 8 when his grandmother gave him a 19th century Dutch coin. After a brief hiatus in his early teens, he rediscovered numismatics, initially collecting Dutch coins before focusing on the coinage of the United States through a Guide Book of U.S. Coins he got for his 15th birthday.

Dennis became involved in American numismatics while still living in the Netherlands and was active on various coin-related Internet message boards. After attending numerous shows in the United States he moved to California in 2011. In 2014 he founded VOC Numismatics, which specialized in historic world coinage but also offered world paper money, which soon became his passion. After deciding to specialize in world paper money he founded World Banknote Auctions in 2020, which surpassed $7 million in sales in 2023 and was acquired by Stack’s Bowers Galleries in 2024.

His personal numismatic interests include banknotes of the Netherlands and its colonies and Liberty Seated coinage of the United States. While numismatics is his first passion Dennis has a keen interest in history, holding a Bachelor’s in history from Southern New Hampshire University. Dennis is a lifetime member of the American Numismatic Association (ANA), the International Banknote Society (IBNS) and the Society for Paper Money Collectors (SPMC). He is also a member of the Professional Numismatists Guild (PNG) and a member of the American Numismatic Society (ANS).

Over the past decade Aris has established himself as a leading expert in the field of World paper money, having auctioned or brokered tens of millions of dollars’ worth of banknotes, domestically and internationally.

His efforts have aided the rapid growth of the World Paper Department at Stack’s Bowers Galleries and contributed to the growth of the hobby itself.

Aris works closely with dealers, hobbyists, and other firms to finalize private treaty deals such as the record-breaking set of Zanzibar banknotes. In 2017, in collaboration with our Hong Kong office, Aris oversaw the sale of a complete set of People’s Republic of China notes.

Long before Matt discovered coins, he knew he had the collecting gene.  As  early as he can remember, it was always something: rocks in his younger years, and then baseball, basketball and football cards took over as his appreciation for sports developed in early adolescence.  Along the way, the introduction to small groups of coins saved by family members would spark a lifelong passion. 
Not long after getting the coin “bug,” eBay played a huge role in the development of the career side of his aspirations.  While selling rocks or cards at a profit was virtually impossible, the fledgling online auction venue presented real opportunities for a teenager to make some money in coins. Matt was able to do this by offering a pleasing presentation and excellent customer service.  Since that time, Matt has spent nearly 15 years at several prominent international auction houses, where he honed his craft, never forgetting his humble foundation: a commitment to customer service that brought his earliest successes.
Still a collector, Matt appreciates a broad spectrum of numismatic disciplines.  While the diversity of world and ancient coins receives the majority of Matt’s day-to-day attention, he still frequently finds himself searching for additions to his collection of medals and tokens depicting George Washington.  Because of their iconography, Matt also has a growing collection of Latin American coins. Depicting suns with faces, soaring mountains and native landscapes, he believes this area of coins parallels the beauty of painted art more closely than any other.

Since 2017, Chris has served as an auctioneer and numismatist at Stack’s Bowers Galleries. He is responsible for identifying and evaluating all incoming consignments, collections, and preparing them for auction. His favorite coin motifs are the Draped Bust and Gobrecht silver dollar designs. Highlights of his career as an auctioneer include the sale of two 1804 silver dollars, one from the Pogue Collection and one from the Larry H. Miller Collection, as well as an 1894-S Barber dime.

John has been involved in numismatics for over 35 years. Previous to relocating to our corporate headquarters in California, John worked with Q. David Bowers in our Wolfeboro, New Hampshire office for 15 years. During that time he worked with consignors guiding their collections through the auction process under the firm names Auctions by Bowers and Merena, American Numismatic Rarities, Stack’s, and Stack’s Bowers Galleries.

John is one of our primary contacts for auction consignments, and personally oversees many aspects of our auction presentations. He has worked with thousands of consignments over the years, including such well-known names as Eliasberg, Norweb, Bass, Pogue, and many others that would be readily recognized from our catalogs. His numismatic interests cover a broad spectrum but are presently focused mostly on American numismatics.

In addition to working with consignors, he regularly catalogs special projects including, most recently, the Twin Leaf Collections of United States Large Cents and State Coppers, Washington medals from the William Spohn Baker Collection on behalf of the Historical Society of Pennsylvania, the Larry Ness Collection of Indian Peace Medals and the D. Brent Pogue Numismatic Library. Earlier projects of note include our presentations of the American Bank Note Company Archives, the archives of Louis E. Eliasberg, Sr., the treasure coins of the S.S.

As a member of a family with three generations of numismatists, it was with great anticipation that Kyle Ponterio continued his family tradition. Kyle joined Ponterio & Associates in 2005, when he started out packaging in the shipping room, along with imaging for the print and online catalogs. Soon after, with the guidance of his father Rick Ponterio, and brother Kent Ponterio, he began learning numismatics at a rapid pace. He then started cataloging coins for auction, doing numismatic research, and buying and selling coins, as the latest numismatic specialist at Stack's Bowers Galleries.

Although Kyle credits his father and brother for his success in numismatics, he brings a fresh new pair of eyes to the company. He enjoys traveling to shows because it gives him the opportunity to look at other's cases and enjoy their collections. Kyle collects sun face coins and necessity money. He is an American Numismatic Association (ANA) member, and also attends monthly meetings of the Greater Orange County Coin Club.​​​

Richard Ponterio began collecting coins as a young boy at about the age of 10. His interests in numismatics first peaked while working for his uncle who owned a vending machine company. During the summer, Rick would accompany his uncle along his route, re-stocking the machines and collecting the monies which had been deposited. At the end of each day, the two of them would search through the coins for dates and varieties they needed for their collections. In 1972 he decided to make numismatics his full-time profession.​​​​

From 1974–1982, he helped co-found the firm Ponterio & Wyatt, conducting mail bid auctions, price lists, and attending major coin shows. In 1982, he formed the company Ponterio & Associates, which was accepted into the International Association of Professional Numismatist (IAPN) in 1988. He also served on the executive committee of the IAPN for eight years. He joined the Professional Numismatists Guild (PNG) in 1979, and served on its board of directors for six Years. He is an ANA life member and is the president of the New York International Numismatics Convention.​

Steve Price started collecting coins at the age of 9. After serving in the Marine Corps, Steve pursued his passion for numismatics and opened his coin store, Penny Lane Coin, in Costa Mesa, California. Shortly after opening his store he began working as a consultant for Stack’s Bowers Galleries, a position that soon developed into a full time job with the company. Steve’s area of expertise is United States coins, a field in which he is well versed in market values. He also enjoys research on varieties and mint errors.​

Larry spent the early part of his life in Texas, later moving to the Saint Louis, Missouri area, where he now resides. A lifelong coin collector, Larry attributes his passion for numismatics to his parents, who introduced him to the hobby at an early age by encouraging collecting wheat cents from circulation and saving up to buy the occasional Morgan dollar from the local coin shop. Larry’s collection is always changing but he has a particular fondness for high end United State type coins and the Spanish colonial coinage of Mexico.

A maker / engineer by nature, it was not long before Larry looked to combine his loves of technology and numismatics, creating innovations including Stack’s Bowers Galleries’ patent pending technology: Coins in Motion. Coins in Motion creates high resolution coin animations that accurately capture the in-hand visual appeal of rare coins and other numismatic treasures.

Larry spends much of his free time cultivating the next generation of coin collectors, including by creating and producing content for online locations where the younger generations gather – YouTube, Reddit, Instagram, etc. He has been on the moderation team for Reddit.com/r/coins for the better part of a decade, a community that has seen a nearly 700% growth in membership (to over 71,000 by the end of 2020). These are almost exclusively younger collectors. Larry also maintains an active numismatic YouTube channel with over 100 videos.

With over 20 years of experience as a professional numismatist, Peter Treglia brings a wealth of knowledge to his position as Director of Currency for Stack’s Bowers Galleries. He purchased his first coin at the age of 14, became a dealer almost immediately at age 15, and quickly discovered paper money, thanks to the Internet. After collecting paper money for about a year, Peter started selling notes on eBay. Once he realized that he could make money-trading currency, he immediately became hooked.

In February 2005, Peter was hired as one of the five original currency graders for Paper Money Guaranty (PMG).

Soon after, Spectrum Group International CEO Greg Roberts asked him to lead the Spectrum Numismatics (now Stack’s Bowers Galleries) currency division. Since the Stack’s Bowers Galleries/Spectrum Numismatics/Teletrade merger, he has overseen the Stack’s Bowers Galleries paper money cataloging and consignment teams, in addition to his primary duties buying currency.

Peter is a Life Member of the American Numismatic Association (ANA) and the Society of Paper Money Collectors (SPMC), and is also a member and Past President of the Professional Currency Dealers Association (PCDA).
