Collectible coins from the United States, particularly the Two and a Half Dollar coins, also known as "Quarter Eagles," hold significant value for numismatists. The 1860 Philadelphia Mint produced various notable coins, including patterns and trial coins, which were experimental pieces created to test new designs or minting processes. These rare items often feature unique designs and are sought after for their historical significance and limited mintage, making them prized possessions among collectors.
