Introduced as part of the Second Issue, the bronzing process was the brainchild of one Spencer M. Clark who served as the first Superintendent of the National Currency Bureau which later became known as the Bureau of Engraving & Printing.
The bronzing process was fairly uncomplicated, and involved a thin layer of strategically placed adhesive and a subsequent application of bronzing powder. However the powder was not easy to work with per various numismatic texts. This feature made its initial appearance on the Second Issue of notes as part of an ovoid arrangement that enclosed the portrait of George Washington. It was soon carried over with the Third Issue and best reflects a simplified measure where the bronze powder was mixed with ink.
From a collecting standpoint, finding examples that feature this short-lived distinction isn’t difficult owing to the large quantities of notes produced under the Third Issue which amounted to an estimated $86,000,000. Yet it can be more difficult to locate a specimen where the bronzing reacts to light as those can be scarce.
Typically, the bronzing on Second Issue pieces is dull in color compared to that seen on the Third Issue. The Third Issue was much more distinct yet tended to darken with age. The bronzed overprint was very intricate as evidenced by the 25 and 50 Cent Fractionals issued under the Third Series. It offers a particularly striking effect, one that was carried over onto contemporary Compound Interest Treasury Notes.
Collectors will have the chance to acquire various specimens of this short-lived feature over a number of upcoming auctions including the Spring 2025 Showcase Auction.
