I've gotten a few cents over the years that have the masonic symbol stamped on them, but none that have been deformed by any sort of punch. The "square and G" is just stamped on the field to the right of Lincolns face.

I think I was handsorting when I found one like you've mentioned..... mine was punched at the base of Lincoln, so on the raised surface... not simple and sleek, but a heavy punch.... I can imagine in it would jam the machine.
