The P50c refers to a fifty-cent piece pattern coin from the United States, created in 1865. Patterns are trial coins made by the U.S. Mint to test new designs, compositions, or sizes before official production. The P50c patterns were part of an effort to introduce new coinage during a period of significant change in American currency. Due to their limited mintage and unique design features, these coins are highly sought after by collectors and can command high prices in the numismatic market.
