DO NOT attempt to EVALUATE your own coins. If you are not a professional numismatist, your attempts to evaluate your coins will only result in false information and frustration. Numismatics is a specialty field. It requires years of experience to authenticate and evaluate coins. The value of a coin is based on condition and rarity. Market values fluctuate daily. While the price in a book or on eBay may seem attractive, it’s not likely your coin will possess the same value.
