That is the hardest to see from photos, because we don't have a size comparison in photos. Also seems to have wear on the devices this can cause some flattening of the letters.
Any help? I submit Wexler's example shows flattening as well. You have to love the detail on the wheat stalks for 108 years old on a circulated coin. It is subjective, but I submit the dot between the E and P on this coin is thicker than Wexler's example.
Post the link to Wexler's DDR-001, maybe there'll be images there that people can compare your coins to and hopefully get a better response. I like your coin tho, nice detail!
