If it had been slabbed as ok then it would of definately gone higher or atleast more interested bidders before the auction went live ,not just attracting more interest in the US but here also.
A couple of people i know were both concerned about the condition of the coin looking at the picture and took that into consideration before the auction went live ,maybe the coin had been slabbed.
Hopefully the coin went to a collector who hasnt got one though ,like jerry with the F90 (Hat off) rather than the same people / person possibly bidding the price up or buying others.
