MattI'll go with $40k then as the difference between the value of the cancelled and uncanceled cards unless someone else wants to disagree.
So, the gives the following trade:
3 sets of US Caramel Baseball cards, valued at $270,00 traded in for a baseball glove valued at $25 and the 3 sets of redeemed cards, valued at $140,000 for a net loss of $129,975
That's a BAD trade 
anything worse?
