PCGS SP Grade
I know this has been discussed before, but I'm still not sure I fully understand the PCGS SP grade. Is it a different definition for classics than it is for moderns? For moderns, does it just mean non-standard finish/strike (i.e. SMS coins, Satin Finish, Enhanced Uncirculated finish, etc.)? It seems that many of these modern coins that are given an SP grade are struck on specially prepared blanks, and struck multiple times. Those should be considered proofs, right?
Anyway, I'd appreciate any clarification you guys might offer. Thanks!
