Die and Hub Trials, also known as splashers, are experimental pieces created during the coin design process. These trials were often struck in very limited quantities to test new designs, dies, or minting techniques. The year 1820 in Philadelphia is notable for various coinage innovations, and pieces from this era are particularly sought after by collectors for their historical significance and rarity. Collectors value these trials not only for their artistic merit but also for their role in the evolution of U.S. coinage.
