Ive been online trading for a long time, and running into a situation I dont know quite how to handle. As we all know the sale price of a card can vary widely versus the book value of a particular card. The issue I am having is when I am trading a card that is selling for above book value for a card or cards that is selling for substantially below book value. I try to introduce SV as an alternative to valuing the trade vs book value and the other trader doesnt understand...they keep telling me its book value or no deal. But in my opinion if the sale values are the same, then its an even swap, even the BV are widely different. Not sure why that is a foreign concept as at some point we all had to buy some of the cards we have for cash money. So I guess the question is how do I balance the scales? On a $200 trade, the book values could be even, but one side could be trading $150 sale value of cards and the other side could be trading $75 worth of SV cards. Any thoughts or suggestions? thanks rich
