A numismatist is a person who collects coins. Coin collectors value a coin based primarily on its date, condition and place of origin. Coins that contain production errors also carry a high value for collectors.
Collectors may value a coin from between a couple cents to over $10,000. Rare coins that were produced in small numbers are generally worth more than coins intended exclusively for circulation. Older coins are worth more than newer coins. Coin collectors grade coin condition on a scale, with the most valuable coins rated as uncirculated. Coins that have been worn down or damaged command a lower price.
