I found 2 interesting things on this 1978
LMC that I will talk about today.
1. The ER in "LIBERTY" looks different than the rest of the lettering:

2. There is like a repunched U next to "Unum" in "E PLURIBUS UNUM" Is it doubling?


I understand the dot is supposed to be there, but under it there is like a repunched U or something. Is it an error?
