Thanks for information, guys.
Agree that old "book" values are meaningless and today's pricing is a matter of "what the market will bear" or what 2 guys at an auction are willing to pay. I have numerous value guides from the 90's and it's fun(?) to see values from 20+ years ago. If I knew then what was going to happen with this hobby, I would have scrapped my 401K and bought high-grade gas & oil items.
