SS, the person who gave (sold, actually) me the coin is from a very rural area where, says he, it was found in a field. As I'm familiar with it, the entire area was settled by Greeks and later Romans, not to mention the Pharaonic folks before them. He showed me the coin, and asked me to make an offer. I went to research it after that.
As for tourist trinkets: actually, I'm quite familiar with the tourist markets in Egypt, as I'm lived here for four years now. They don't sell much that looks antique here. What's more, Egyptian workmanship, unlike in centuries and millennia past, is very low quality. If it is a copy, I wonder how he got it to start with. I'm not familiar with copies coming out of Egypt, but, as I said, I'm a complete amateur.
And I still have no idea about that inclusion. Curiouser and curiouser.
Mackaydon ... as for the date, I'm just guessing. Nobody told me anything about the coin. The guy showed it to me, and I looked it up to see what it was. My description is based off the coin you found, and that SS cites above.
My date attribution could easily be entirely wrong. I see a letter on the reverse right that looks to be part of a "K." Below the horse I see an "A," but the inclusion might be hiding something, as could the edge of the coin. It could be something else entirely. Are you (or SS) seeing something other than L-K-A? I could only dream of an unrecorded type or variation! When opportunity presents, I'll have it slabbed (if I'm using the term correctly).

this tells you just about everthing that's wrong about it, the patina and flan difference can be explained, but not the weight difference.
