142.4 grains. A hook neck eagle flies left on the obverse with 13 stars around the border and the date 1855 below. The reverse exhibits the denomination ONE CENT in the center surrounded by a laurel wreath with the legend UNITED STATES OF AMERICA around the border. Struck in copper (100%, as denoted on the NGC insert) on a jumbo planchet with a plain edge.
An intriguing piece, the weight of this coin dwarfs that of all other examples of Judd-167 of which we are aware. Most examples weigh somewhere in the range of 90 to 100 grains, and the heaviest specimen listed in the 1994 reference United States Patterns and Related Issues by Andrew W. Pollock III weighs in at only 112 grains. Also of note is the fact that there is no evidence of either clashmarks or the diagonal die line on the reverse between the letters NI un UNITED that are seen on most examples.
The striking quality of this coin is truly impressive, both sides fully delineated over even the most intricate elements of the design. The fields are aglow with modest, yet appreciable reflectivity, and they also reveal myriad die polish lines (as made) that should not be confused with detracting hairlines or other handling marks. Bathed in rich rose-brown color, and sure to serve as a centerpiece in the finest pattern collection. Rarity-5 overall as a type, yet almost certainly unique for a Judd-167 example struck on such a heavy planchet.
The following commentary is provided by a pattern specialist who has compiled an impressive amount of information on this specimen:
Though never mentioned in any of the Judd book's first 10 editions or in Pollock, this coin's existence was confirmed as early as April of 1863 in Bangs, Merwin & Co.'s Woodward sale. Auction lot number 2211 stated: 'Flying Eagle Cent, pure copper, on planchet of double thickness, exceedingly rare, very few examples of this variety struck.' The next reference to a thick planchet copper 1855 Flying Eagle Cent was in Bangs, Merwin's April 1877 Jenks sale, in lot number 409, which stated: '1855 Cent. Flying Eagle. Copper. Thick planchet.' According to notations in the auction catalog, this specimen sold for $0.75. Robert Coulton Davis' September 1885 [installment of his serial article 'Pattern and Experimental Issues of the U.S. Mint' published in] The Coin Collector's Journal also confirmed this coin's existence...wherein it stated: 'Occurs upon thick and thin planchets.'
Additional commentary about this important coin can be found in American Numismatic Rarities' March 2005 Richard Jewell Collection sale (where the coin was pedigreed to the Hogan Pond Collection), lot 1008, where it states:
The dies were quickly made up with no thought of imparting a highly polished Proof surface to them with the result that prominent diagonal striae are seen on both sides. At the rim at the top, not particularly easy to see, there seems to be a 'cud' or filled area, adding interest--this commencing from about [the 12 o'clock] position and ending at [4 o'clock].
