Identification of a strange Antoninus Pius Bono Eve silver coin

I recently purchased an Antoninus Pius coin. I have done my best to research it but can't find anything. It reads Bono Eve but the only Antoninus Pius coin with Bono Eve inscribed is a Bronze As yet mine is silver .  Link : N#260950

So my first question is has anyone seen this coin before ? if so do you have any information on it. And my second question is if no one has seen this before what do people believe it to be ?

The legend reads Antoninvs avg pivs - Pptfpcosiii

The coin has a width of 1 Inch and is made of silver

It doesn't make any sense that such a coin would be made of silver.  It is the right size to be an As, and it features the letters S C on the reverse which only occur on bronze coinage at this time.   It is also seems to have a casting seem on the edge.  All these factors seem to add up to a modern forgery.
