  Molybdenum commemorative medallion. 
From the eBay seller's listing:These pure molybdenum coins are the only 1 ounce molybdenum coins in the world ( as far as I know). They have been hand cut from .9995 pure molybdenum rod ( certificate with coin giving complete analysis) , hand polished and then deburred and stamped using special steel for the dies. The minting is of the highest quality. The coins weigh over 1 ounce each with some small variation because they are hand cut. Wow, what an odd way to make coin blanks, normally they are stamped from sheet, not cut from a rod.  This may explain the oddly mottled surface texture.
