Patterns are experimental coin designs created by the U.S. Mint to test new concepts or technologies. The 1866 P10c pattern, specifically, features a design proposed for the 10-cent piece and is significant for its unique artistic elements and historical context. Such pieces are typically struck in limited quantities and are highly sought after by collectors due to their rarity and significance in numismatic history.
