Once more I have a confusing (to me) example with no available/matching listings on Variety Vista or Doubleddie.

Does anyone else see the RPM &/or doubling? Neat collar clash at least.

Thanks for looking!

Thank you, Errers!

In an attempt to learn; I have to admit I'm confused, as I didn't believe machine or Die Deterioration Doubling resulted in even-height separation of serifs, etc., but that's the response I seem to be getting on most of what I've post (I don't mean to say from you, specifically, just in general ).

The Kennedy halves I have with Master Die Doubling on the obverse look no different to me than what I've pointed to here, not that this is a Kennedy half, but they're a good example of confirmed minor doubling on a modern other than a Lincoln Cent for me to reference.

Truly just trying to understand, not dispute your assessment. Does Machine Doubling appear different on a proof due to the surface finish?

Here's a... creatively edited... side by side to a PCGS photo of the same year proof, take a look at the torch flames:

1977-S-Roosevelt-Dime-Collar-Clash-Proof-RPM-/-DD?

I can see the separation on the flame under the "E" in "STATES" in my blurry zoomed out shot. No features have a flat or shelf-like appearance.

Again, thank you for the reply!

Edited to say oops, I take that back, "US UNU" definitely looks like Machine Doubling... I wasn't focused there.

No problem, MNP. I don't know if you know this yet or not, but proof coins are struck twice or more. That increases the likelihood of Machine Doubling to happen more.

Ah, see, I did not!

Glad I asked specifically about it being a proof, thanks again!

Remember on proofs they are struck twice to attain the high quality strike - so there can be things seen under high mag that otherwise won't be seen on a business strike.

"Proof coins are typically struck at least twice by the same die, a process that involves using specially polished dies and planchets (blanks) and striking them under high pressure to create a highly detailed and brilliant mirror-like finish that contrasts with a frosted, matte design."

Marve65, thank you as well.

This makes a lot of sense, of course, I just hadn't put the two together.
