Die and Hub Trials, also known as splashers, are experimental pieces created by minting facilities to test new designs or die configurations. In the context of US coins, the DT5c refers to a specific trial associated with the 1866 five-cent coin (nickel) minted in Philadelphia. These pieces are produced in limited quantities and often feature experimental or varied designs that differ from the final production coins, making them highly sought after by collectors due to their rarity and historical significance. Their unique attributes provide valuable insights into the coinage process and the evolution of US currency.
