Well, good question (how to price these), Tenbobbit! As I said before, despite the wear and pitting, this is a good example of a very rare coin. Even Schatz over at Forum, who has the most extensive collection of Parthians that I've ever seen online, does not have a Sellwood 12.12. Having said that, I suspect that few collectors - even Parthian collectors - would understand its significance. Fred Shore's 1993 price guide is of no help, since he clumps all bronze Mithradates I "large flan" types together with an "R2" rating, and a $200 value for this (fine) grade...he does not distinguish between the varied reverses of Sellwood type 12's, unfortunately. Yours is rarer than others.
Here are a few links with a diversity of prices...there's neither rhyme nor reason here, reflecting the fact that no one seems to have a clue how to list these:
$495 (listed as an AE 4 chalkous, it's a tetrachalkous, like yours):
http://www.parscoins.com/itemdetail...S&item=12262$29! (someone got a sweet deal):
http://munzeo.com/coin/kings-parthi...ana-21981930$150 (despite the incorrectly listed denomination, it's another tetrachalkous):
http://www.noble.com.au/auctions/lot?id=115513I would take it off your hands if I collected Parthian AE's, but I only do the AR's. Best wishes.
