Determine where and when the coin was minted by searching the front of the coin. Write down the date and the capital letter beside it. Search for an online coin minting guide to determine if the date and letter indicate a rare mint.
Look at the various points of embossing on the coin to determine the level of wear. Check the ridges around the edge of the coin for any grit or other damage.
Review the coin grading guide linked in the Resources section to determine the best grade for the coin. Bring it to a specialist for a second opinion and confirmation on the grade.
