If you can get Armin Pfender going you ae going to have a wonderful guide/price publication. He is working on the graphic, color version. Without the pictures he has a very extensive listing in published format.

Personally any price guide is just that, a guide. Anone who sells chips and publishes is suspect to me.

Eastman had a list but rather incomplete and I believe about as easy to find as a hens tooth.

My take is that if I have two one is trash and if I do not have one then it is a treasure.

Wishing you enough,
