To know for certain you would need to draw key point lines from the MM to check positioning - then, if they were the same - find markers on the coins that were identical as well. Not sure why one would want to do that with three machine doubled coins, but to each his own...
Could be Could be....for the top two fer sure. The 3rd one has a much thinner "9", to my eye. The top two seem to share a crease common to the "4". (Now I'm off to scan my '44 stash) Thanks for the Heads Up! (Why is it the "9"'s always seem to bear the brunt?) edited to add a funky "9" on my own
