I haven’t a clue where or whenI got this but I’ve had it at least 25 years. That is based on the other items that were in the same box. I have no recollection of it at all. I see blank cent planchets all the time but not dimes. This is considered the obverse but I can’t tell for sure. Lol
There is no Obverse or Reverse on Blanks. Only when it is struck the sides are determined. If it is a raised rim blank that was passed through the upsetting mill both sides will looks the same. Also Type 1 Blank - no upraised rim Type 2 Planchet - upraised rim
I actually have one of those. Being a dime collector I found a dealer who sold the planchets as novelties at a show and I had to buy one.
I am gonna have to find it. Haven't seen it in years. Might have to search my accumulated dimes think I threw it in a roll somewhere.
