Odd Looking Coin

Yup. It is a counterfeit. This type is a widely faked.

It's a very commonly seen replica of an ancient silver coin from the Greek colony of Gela on the island of Sicily. The huge hole in the middle of the man-headed-bull's neck is not present on genuine coins of this type; it's put there by whoever made the copies, to hold a blob of glue for attaching onto a promotional card.

We see them here on the forum about three or four times a year; do a forum search for "gela copy" and you'll find over a dozen threads with similar examples. here's the most recent, Here's another typical example.

I don't think we know for sure where these copies came from, but they're so widespread they must have been part of some kind of Reader's Digest style promotional giveaway.

I agree with Sap's opinion - as I remember these fake "coins" attached to promotional mailings in the '50's and '60's from Reader's Digest. In fact, I have a similar "Greek" fake somewhere in my token collection that I'm sure dates back about 60 years.
