Thank you for rotating the picture. I took the picture straight up but for some reason it posted sideways. And I couldn't figure out how to fix it. So thank you again. As for the holder, it was made by a company called Encore Plastics. It produces plastics/acrylic accessories for the medical field. I've only seen another Encore holder that was for a gold krugerang set. The fact that this holder was tailored to the size of the
Buffalo nickel, and the fact that I can't find other examples of this holder besides the one mentioned above makes me unsure if both the certificate and the holder were part of this 1984 ANACS experiment. Or just the certificate by itself. And thank you again. I was lucky for sure.
