Is Numismatic BU The Term Used For PL Coins Post 1968?

Thanks okie that was a good read, but I always though PL coins had more polishing done then business strike, and some were struck up to twice making the minting process slightly different, at least for what I thought I know about pre68 coins. I haven't looked at enough examples but PL has a mirror field with older coins where as with new coins it's basically the exact same. So if new coins uncirculated or circulated are the exact same then how is it possible to determine a coin as uncirculated or MS? If there is no difference at all with list 68 uncirculated coins and business struck coins then thats kind of a huge grading flaw.

Edit:to me it seems like from 67 or higher grading with modern coins that it wouldn't grade MS67 or MS68 it would read numismatic BU MS67+? I still don't quite understand how they can differentiate between a high grade business strike and a high grade numismatic BU if they are essentially the same coin one just ha deled a little better.

With silver coinage isn't there a clear difference or is it the same thing? It's a really confusing concept even after reading all those opinions.

So was it ICCS that switched in 1981 to label PL as numismatic BU? And is there actually any difference between uncirculated stuck coins and business stuck coins?

And as for a difference in actual striking practice between a Pl and business strike coin is there a tell tale sign between one or the other? This was kinda my main focus is the difference between PL or not or whatever numismatic BU is.

Let's say I pulled a fresh 2022 quarter out if a circulation roll or bank uncirculated roll, is it automatically NBU? Or for example there is an NBU 68 graded 1987 cent from ICCS would that be the same price scale as a business strike or a PL? Or is everything so messed up here it's just a roll of the dice lol?

I just don't get the NBU lable, what the difference between an NBU ms 67 vs a generic grade ms 67.

From what I read and Charlton (an older one, not a Vol 1), take look at what Charlton says about proof-like and specimen sets. They stopped PL in 1967. The P-L designation after that means that it describes the finish and nothing more, no extra strikes or special dies. It is an uncirc coin and can by called BU or MS or NBU, whatever you want. Until all the TPG's and publishers get their act together, confusion will continue to reign. Just forget the term P-L for anything after 1967/8.

One theory that I like is that it was created by pressure from key dealers to maintain their a ability to set higher prices for MS circulating coins rather than compete with a relatively cheap competitor (eg. RCM). With the added benefit of having collectors needing two coins instead of one.

I never underestimate the power of competition.
