With there being such a huge gap between VF and EF there's no way a bidder would cut their self off at VF for this coin whether it's graded or not. I'll pay $300 right now... so I guess you can up your estimate at least that much

... but I still think more. Sure the coin is going to have issues from being dug, but eye appeal counts for a lot, and probably more than a lot of people give it. I'll wait for someone to prove me wrong, but I am thinking more like $500-$800 if you just threw it on ebay. I didn't check any sales, but if EF is over a grand I don't see why bids wouldn't creep up towards that figure. f you wanted to go into detail about it being dug, and the scratches etc, I'm sure you could kill your price, but there's really no reason to because thousands of coins are sold every day with nothing more than the picture. I'm interested to hear what anyone else thinks.
PS: I'll pay $400 right now, so it's worth at least that much!
