I have a $5 Sands arodie up for sale. For argument's sake let's assume someone is cray enough to have the bid up over $30,000+. Now on the day before the auction ends I find 3 boxes of these chips. What do I do? If I make the discovery known, there'll be a whole bunch of bid retractions. With 300 chips, I could expect no more than $50 per chip. Even at that, only 100 or so chips would be sold.

What should I do. More importantly what would you do. Remember $30,000+ is at stake.

Let's also assume that you could really use the money.
