Looking at the coin in hand, I am sure that the reverse has been smoothed down. In the seller's picture, scratches are noticeable; but in my picture, you can make out what looks like (according to the orientation) X X ? ?. There are also some letters barely visible in what looks like the exergue and at 5 o'clock on the reverse, you can make out some of the beaded border. So this may have been modified for use as a token or game piece.
