Collectible coins are items of numismatic interest, often sought after for their historical significance, rarity, and aesthetic appeal. In the United States, notable examples include the Pattern coins from 1849, which were experimental designs intended to test new coin concepts. The California gold rush era produced various die trials, such as the PS 1 pattern, reflecting the burgeoning need for currency in a time of economic expansion. These coins are highly valued by collectors due to their limited mintage and the historical context of their production.
