This piece features an 11-sided inner rim with a lathe-routed shallow mound at the center of each side to simulate the raised relief of an actual coin. A golden champagne hue overlays the silvery surfaces and complements the overall smooth complexion, though trivial scattered marks are visible under magnified inspection. During the development of what would be the Susan B. Antony dollar, the Mint issued these ambiguous patterns to manufacturers of coin counters, coin wrappers and vending machines to evaluate the physical properties of the proposed pieces. While many thousands were likely struck, most were either lost, destroyed, or returned to the Mint, creating a true modern rarity for pattern enthusiasts.,PCGS# 9571. NGC ID: 258Z.,,
