I did a little search on this when I saw it this evening and found the following CCF forum entry from CoinMaster...
https://goccf.com/t/237889The last picture in that post shows a very slight outline of a mark on the left side of Monticello. The die crack from CoinMaster's doesn't match up on mine, but the mark on the left side is a full blown die break with the same shape as CoinMaster's in my pictures. I thought the similarity to the post was neat.
