About the Greek Token:
I believe that I have pieced together some insight based on my study of Classics in college...
The name on the obverse of the token is I believe for a hotel or resort the "Xenios Zeus"...I base this on the initials 'E.O.T.' which I believe is the Greece Tourism Board's acronym.
The quote on the reverse, PROS GAR DIOS EISIN HAPANTES XEINOI TE PTOCHOI TE DOSIN D'OLIG(H)E TE PHIL(H)E TE, reminds me of a quote from a past greek class I know I was supposed to learn more than I did (Homer's Odyssey I would wager) "treating foreigners and the poor well" but I don't understand the whole construction...I'll keep looking for more info, but I think it's some kind of tourism/souvenier piece.
Wait--I found it, it is from the Odyssey, and is translated by the Tufts project as:
for from Zeus are all strangers and beggars, and a gift, though small, is welcome.
This token must be the 'small gift.'
