Can't answer that, since I'm not a collector, but you might ask the question at one of the other forums out there that do have a collector section. Only place I go that has something like that is
http://www.knifenetwork.com; try your question in the Production Knives forum. You have to join/register first before you can ask. Local bookstore, of course; look in the collectibles area for the usual knife collectors quides there.
