Alex J. Barna Coins & Currency is a tiny shop on Darby Road; blink and risk missing it. But the size of the storefront belies the great quantity of rare and valuable coins inside. After many years collecting comic books and trading cards, the owner began to focus on managing and building collections of U.S. coins and currency for sale to beginning and intermediate enthusiasts. When not in his shop, the owner can be found at a number of trade shows throughout the area. There is a big parking lot near the shop, with plenty of spaces on Darby Road just on the other side of Eagle Road.
