I just found a 2011-D Vicksburg quarter which appears to be on a proof planchet. Has anyone seen or heard of one before? I noticed it because the background is much more shiny than a normal business strike and the reeded edge is more squareish like a proof coin. It is definitely cupra-nickel and not silver. Would appreciate any thoughts or suggestions on how to verify this coin. Thanks!

Posting a picture would help some of the resident experts on here.

It probably isn't struck on a proof planchet, but may have proof-like surfaces. Also, a sqaured off reeding has little to do with the original planchet unless there is a difference in hardness.

I have seen some stunningly proof like D mint ATBs. My guess would be you have one like that. Post pics!

I think first you have to question what were proof planchets doing in the Denver Mint ?

San Francisco ships rejected proof planchets to Denver for use in business strike production.

Still? I thought that was a practice long gone.

Thank you for the inputs. I'll try to get a pic on for further evaluation. I was wondering, also, how a proof planchet got to Denver. Does anyone else know whether SF is still sending their Proof planchet rejects to Denver?

I've found three Acadia-D Quarters and a 2012-D Dime that could be Proof planchets.
The Dime seems to have a slight frost effect on the devices (looking somewhat like a pre-1980 Proof).
The Quarters have no frost effect.

Frost effect on proofs comes from the die not the planchets.

I did say "slight", and it's nothing like the frost effect seen on 1980's-up Proofs (especially not like the grainy 2009-up frosting as you'd see on a 2012-S Proof Dime).
In hand, it looks like my Airtited 1969-S Dime.
In the Morgan days, many of the business strike coins struck with fresh dies were Prooflike, the best examples being DMPL, and a few of those had a natural frost effect on the devices.
My Dime could thus be a new (business strike, for sure!) die striking a rejected Proof planchet.
