First, welcome to the neighborhood! You do realize that the most recent posts on this thread are almost 5 years old, don't you? Chris
Can you post images of the pieces? If they are examples of some of the test pieces they will have collector value. What that value would be would be difficult to impossible to say. The value of something like this that appears so seldom could only be determined by what someone would pay for it at an open auction.
Does anyone know how to contact "robc" ? I am working on detailed research into the INCO and 1977-78 Gould coin composition tests and would love to learn more from "robc." (I think this is Robert Crawford, who was a key participant in the 1963-65 work.) Roger W. Burdette
Best of luck Roger, Robc only came aboard 5 years ago for a post or 2 and then no more to be seen. I did a quick search for the company , but no luck. Jim
I've written letters to Mr. Crawford and a couple of others connected with the INCO project. Not sure I have the correct people, though. Most are in their mid-80s. Not sure what information is out there after so long, but time is critical for contacting participants.
