Die and Hub Trials and Splashers are experimental strike coins made to test the dies and hubs used in production. These pieces were created to assess striking characteristics before mass production, often resulting in unique designs or errors. The term "P 10" may refer to a specific designation within a catalog system for such trial coins. The year 1849 is significant in U.S. coinage history, particularly related to the California Gold Rush, which impacted the creation of numerous gold coins. Paris was influential in minting technology, contributing to advancements in coin production techniques during this period.
