Found this, is this a rpm or something else? What do you think? Thank you

Mintmarks were no longer individually punched into master dies after about 1990, so cannot be an RPM.

 

What @expat said.

 

Ok thank you I'll take it as it's just a die that moved south.

 

I looked at it little more maybe a ddo? Here's more pictures.

 

Nope. What I call
reflective doubling" or" "Microscopitis". Too darn close examining.

 

Thank you

 

What I am seeing is either Machine doubling or what is called flat field doubling. My understanding of flat field doubling is that since proofs are struck twice, if machine doubling occurs on the first strike, the second can then flatten that machine doubled portion so that it is flush with the field.

 

I think the proofs are struck twice and with more pressure. That would account for it.
