German Iron Cross medal

This medal is in the shape of a cross. The cross is black and outlined in silver. On the obverse side it features a "W" in its center. Above the W is a crown and below the W is the written "1914." On the reverse it features leaves in the middle. Above them is a crown and the letters "FW." Below the leaves is the year "1813." A suspension ring is above the medal that presumably would have attached to a ribbon, which is now missing.
