If you are looking for a fascinating collection, then consider collecting a jetton. Produced from the 13th century to the 17th century, students often used these tokens to learn to count on a board similar to an abacus. Players also used these round pieces of metal to play games, similar to the modern poker chips. Most jettons had religious or educational institutions represented on them. The best place to start collecting a jetton, or add to your collection, is from the top-rated sellers on eBay. Many even offer free shipping. It is also a great place to get ancient coins or other collectibles to add to your collection.
