I have only one Sands $5 which I sell for $30,000. I use the money to pay mounting debt.

A month after the auction ends I find 3 boxes. Do I offer the buyer a refund of $30,000 and go into debt to raise the money.

Do I destroy the chips so the buyers price is protected?

Do I just start selling them for $100 each. Of course the original buyer is screwed.

Or do I compromise and save 3 or 4 chips, thus partially protectecting the original sell and sell the others VERY slowly

Remember, I'm not actually doing any of this. Please don't attack me.
