Please Help Identify This Coin Or The Text On It?

The letters are Greek and seem to spell TESSA NUY, which I have no idea what it could mean if anything. I don't know very much about Greek coins, but what I do know is that it doesn't look right to me. I believe that it is a tourist piece.

Hello and welcome.

To see some genuine examples of coins with this design, have a look at this Wildwinds page.

It is indeed supposed to be a silver coin, and yours does not appear to be silver; furthermore, Thessaly is in northern Greece, a long way from Cyprus. Further still, it is illegal in Cyprus to sell genuine ancient coins to tourists. Selling fakes to tourists, however, is perfectly legal there.

So overall, I do not think that your chances of it being a genuine ancient coin are very high.
