Alexander III 336 - 323 gold Stater Macedonia Amphipolis Athena with Corinthian helmet on obv. Nike standing left holding wreath trident in field 2,000 - 2,500 (give or take hard to say exactl, low detail shot) IF it is authentic
forgive my ignorance, as I know nothing of ancient coins, but isn't the fact that it is in an ICG holder a wonderful indication that it is in fact authentic?
Not in my opinion...There are some real ancients experts out there I would trust, this isnt one of them. But to each his own. http://www.davidrsear.com/ ^^ IMO the premier authority on ancients http://www.thebritishmuseum.ac.uk/ ^^ others
Yes he does. There are others besides him as well who perform a very similar service. But to the best of my knowledge none of them actually slab the coins. Because of that, I do not think of him, or the others, when talking about a TPG in the traditional sense.
