Otacilia Antoninianus - Real Or Not?

Its fake. Very much so. Cast (you can tell by the surfaces) and then the edge was filed to hide the seam. They've done a poor job of it - big file marks, missed a bubble in the edge, the faces have some blobs where the impression has been damaged before casting. Its also much too thick...Perhaps its a sestertius cast in silver for a jewellery piece. The reverse lettering appears to be like that on a sestertius.

I queried this coin in a thread a week or so back. I contacted the seller who told me that he had bought as genuine from a dealer and was selling it as a genuine coin, however, if the buyer complained he would refund the money. Says it all really.

Report that dealer if you're privy with ebay. I'm not ;*(
