Doug:

I agree with what Steve says.

Chips that are listed for $100 in the price guides, often sell for $20-$30 on Ebay.

Just like baseball cards that my 13 year-old son collects that list for $100 in Beckett, often sell for $20-$30 on Ebay.

No difference. it's the economy. Not the hobby.

But don't you think a price guide author in any hobby, that has a large degree of influence on the hobby market should be very careful with what he says?
