Do you guys think this is an unstruck zinc planchet? It weighs 2.52 grams. There doesn't appear to be any damage to the rim, like it was sanded down. There appears to be a grain running through each side, but it doesn't look scratched. I found this roll searching a few minutes ago. Thanks all.
I looked on ebay. You can get them for around $3 plus shipping. This one isn't a blank though. It's an unstruck planchet. A blank hasn't been through the upset mill. This one has.
