Join a numismatics association or society, such as the American Numismatics Association. Numismatics is the study of coins and money. The associations will often hold shows where coins are displayed. This offers first-hand education for those who are new to the field. Members will identify their coins and discuss their collections.
Visit a museum that has a collection of antique coins. This will allow you to see authentic antique coins and learn details about the location in which they were found and how they were produced.
Examine the color, patina and texture of the coin. It should be uneven because of exposure to the elements. Antique coins often have scratches and cracks. Fake coins can be identified if the color is even and there is little effect from time. An electrotype coin is created by sticking two coins together with a lead center. These coins have a small line that runs around the outside and have a dull sound when they are dropped.
Take your coin to a certified or experienced coin appraiser to identify its authenticity. If you can have more than one appraisal, this will give you a better idea of the value of your coin. You can also compare its authenticity. Both appraisers should be able to tell you the era in which the coin was produced and its age. Take photos of your coin and send to an online appraiser for identification.
Purchase a book on ancient coins for collectors and educate yourself. Some recommended books include: "The Handbook of Roman Imperial Coins" by David Van Meter; "Ancient Coin Collecting" by Wayne Sayles; and "Collecting Greek Coins" by John Anthony.
