Bill was kind enough to put this together showing how the embossing is differently geometry, not different depths, which can fool you sometimes. You have to look at the spacing, and other mold details. For instance observe the little differences in the ampersands. Not the depth, but the shape, the top loop, the direction the tails point, etc. Look at the period spacing, NOT the depth. Depth might change with the age of the molds, but the shape of the letters were cut into hard iron which won't change by buildup of carbon, rust or goo. I'm VERY interested if anyone has any other mold variations to report.

I also make acetate masks to check for even more subtle mold variations and changes. But that's another posting.
