1973 Apaxmai Greek Coin Any Body Speak Greek

It actually reads 'Drachmai' in Greek letters. Greeks have their own alphabet.

'N. Per' and 'I. Stin' are the initials of the engraver.

What you have here is a one year type of a Greek 2 Drachme coin from 1973, when Greece had gotten rid of their royal family and was ruled by 'the colonels'.

I can't say if this coin is worth keeping, as I don't see pictures of the whole coin, just some detail close ups. Most reasons to keep this would be subjective: because you like toe coin, for example.
