Issued by Greece, the host country of the XXVIII Summer Games and the only country authorized to issue the official coinage of the games, this beautiful proof silver crown has a legal tender denomination of 10 Euro and was struck from one ounce of .925 fine silver. It is listed in Krause's Standard Catalog of World Coins - 2007 Premier Edition as KM-193 with a market value of $60 and depicts ancient and modern javelin throwers. This coin would be an excellent addition to any collection of Olympic or world coins.
