Since it was bid on by several people and 2 of them, probably not in possession of a The Chip Rack Book bid over the $60.00 value it definitely has a high value of $105.00. As in everything, people have different values for an item. Here we have an example of 2 people wanting to pay $105.00. And today that is what it was worth to the seller. Just like the stock market, one day $100.00 the next day $75.00.

... and that's my 2 bits worth
