I believe these have been found. Coin Collector Since 1978 Avatar Old Avatar 7070 Eisenhower Australia Canada World CCF Members on eBay CCF eBay Search Engine Report this Post to the Staff

fortcollins Pillar of the Community United States 3638 Posts	Posted 04/23/2026 5:47 pm I was pondering this thread earlier today. What about different denomination coins struck on planchets prepared from the right composition but from the wrong stock during a transition period? I recall hearing about a quarter or quarters struck on quarter-size planchets cut from the rolled thickness of SBA stock in or around 1999 or 2000. The result would be a proper diameter but overweight quarter. I can't recall ever seeing one in real life, but I think I've seen photos or news stories. Report this Post to the Staff
