barrysloateI see Bruce's analogy, and I have to agree with him. I've sold baseball memorabilia over the years that has increased in value tremendously. But I can't call past customers up and ask them to send some more money for that T206 Cobb they bought from me for $100 in 1990. At the time of the transaction it was a fair price.
Likewise, if I'm at a flea market and a dealer offers me a $5000 item for $100, I have no obligation to clue him in. It's every seller's responsibility to do due diligence before putting an item up for sale.
And in the case of the school teacher who sold the Boston Garter, he had a few years to do some research and make an educated decision regarding what to accept for it. And Bruce offered him more than a fair price. Sure, a decade later it looks cheap, but everything increases in value over time.
