1) BU coins- All except third from the left?

2)Proof coins- the three on the right side in the bottom images?
(If there is only one I will say the third from the right.)

Hello all,
1.BU,PR,PR,PR,BU,PR
2.BU,BU,BU,BU,PR,PR,PR
I only posted here because this is the first coin, I have found, that looks so much like a PR Edge and Rim. Petespockets55, thank you. If this happens to be an Upset Error, is it something that happens often? Could it be a BU blank Planchet accidently prepared to be a PR Blank? Is it a weak Strike Circulated PR, that I am just assuming is a BU coin? Thank you all for the help,
Edward M.

Interesting because in the top image used for your questions there is one rim that is noticeably thicker and more reflective than the other proofs. (third from the left)

I got back into the hobby 6 years ago and still have a lot to learn myself so I'm not really the one to answer your questions. I'm not sure if any of them might be impaired proofs because some of the one's you labed as proofs are not highly reflective.

There are a lot of knowledgeable collectors here but I think ANACS might be able to attribute it for you and answer your questions definitively. Because of them being more of an attributor supporting the hobby, rather than just slabbing for the $. They are the only ones I know of that attributes all varieties, not just the FS# ones. I think they do errors also or have people who may know and be able to help you.


EDIT: Which of the coins in Group 1 or 2 is the original coin in the thread?

Sorry, In pic 1, it is 5th coin from the Left. In pic 2., it is the 4th coin from the Left.

That's ok. Thanks.

I've heard rumors that some proof dies may have been repurposed for business strike coins but I don't know how true that might be.
(The "Close Am" and "Wide AM" varieties may have added fuel to this rumor since they are proof and business strike reverses that got switched.)

This has been a question of mine for years actually. I've come actoss circulation coins roll hunting that appeared proof like. I think I asked a question here about a week ago on this about anot her cent I came actoss roll hunting.

Answer I was given was likely a new die pair and collar set up or actual "first strike" scenario.

I'm actually more on the belief that San Francisco uses vertiCal presses and P and D use horizontal, and that for whatever the reason the San Francisco strike is better in some situation even on coins without the S mint mark when they made some business coins to help out. A difference in the press and pressure set up on those first initial few.

Another theory I have is that they are double struck but they don't move, in the same way a proof is made, but the planchet doesn't get the finishing treatment that the proof coin planchet would get.

I don't have an answer really just more questions.

I was asked to contribute to this thread. With respect to the 1969-S cent with the "proof-like" edge and rim, all I see is a well-struck business strike. When coin metal completely fills the rim gutter, you end up with a wide edge and a sharp rim/edge junction.

One other thing. There is no practical way to distinguish between a proof planchet and a business strike planchet once a coin is struck. The strike smooths-out any differences in finish and surface texture.

Thanks Mike but I'm not understanding something correctly and I'm not sure how to word the question.
Aren't both types of planchets prepared differently to attain their respective finishes?

So are you saying that a proof planchet and a business strike planchet will look the same if both are struck by proof dies. (They will end up looking like proof coins?)

And the same combination of planchets will look the same if struck by business dies? (They will end up looking like business strike coins?)

The proof finish is imparted by the highly polished proof dies. I really don't understand the point of polishing the proof planchets. There may be a slight difference in finish noticeable between business strikes struck on normal planchets and business strikes struck on proof planchets, but it's probably quite subtle and not consistently present. I could be wrong, of course.
