I read his post and would take his and everyone's (including mine) advice with a grain of salt. You did neglect to inform the other folks about the heavy encrustation, which to me means that it is way, way older that 1960's. It may be embarassing to admit overcleaning, but we've all done it, and the as found condition is important to mention. I hope you have some as found pics, but don't feel bad if you don't.
I still can't make out the details of the head, face on the obverse. I would love a closeup of that. I have Photoshop and if you want to email me some pics for editing, feel free.
So far I'm with the Minoan theory, but the African connection should be checked out as well.
More power to ya
P.S. I wouldn't waste my time arguing theories. This could take years to figure out and time (at least mine
) is precious.
