not sure what you're expecting here.  Nobody is going to pay 300 BTC for a 100 BTC bar - the added value of the hologram error is maybe worth 2-3 BTC *at most* (if that) - so a max price of 102 or 103 is far more reasonable.  You've already had an offer of 102.5, maybe you should take that and accept the 2.5 BTC profit.
