Ridiculous offers don't have to do with what the BIN is. If by some price guide, be it VCP, SMR, Beckett, etc. the card is booked at X, as long as the offer is at least 50% of X I wouldn't call it ridiculous. You have to allow for the possibility that the buyer only has SMR in front of them and even though SMR may severly undervalue the card compared to past sales, the buyer may be making a reasonable offer using the info they have in front of them. Now, if you get a $200 offer on an SGC 40 CJ WoJo (I did last night
) then it would seem the buyer is just hoping you click "accept" by accident.
