Message:: [QUOTE="GDJMSP, post: 25929436, member: 112"]As mentioned already 2007 is when the TPGs first started slabbing problem coins. If one searches the forum they'll find a great many posts/threads from that time condemning it, applauding it, and discussing it in pretty much every way imaginable. You could also search the numismatic magazine archives and find many articles there as well. Over the years many of the definitions used by PCGS, as well as other TPGs, have changed. And no they didn't all happen at the same time. You can find examples in the PCGS grading book, (2nd edition was 2004), and they'll be different from what is used today; in what they call the Lingo section on their website, and a different section (can't recall exactly what they call it) but it's where they tell you what they will give clean grades and what they will give problem coin designations. You could also use the Way Back Machine (internet archive) and examples there. This is a copy of what the problem coin designations used to be from some years ago. The only way I can find the original creation date of this file is to dig into some of my backups from years ago, and I have no idea which one off the top of my head. But I'll see if I can dig it up. But it does specifically list what you asked about Larry. No GradesPCGS will not grade and encapsulate any coins with the following problems: 82    Filed Rims    Rim(s) and/or edge is filed. 83    Peeling Lamination    Potential for sealing damage. 84    Holed and/or Plugged    Any filled or non-filled hole. 86 No Opinion – our experts are unable to determine a coin’s authenticity – fee not refunded 87 Not Eligible For Service Selected – the coin is too valuable for the chosen service level – fee refunded 90 Questionable Authenticity – the coin is most likely a counterfeit. 91|N-1 Questionable/Artificial Toning (or Questionable Color for copper) 92|N-2 Cleaned – surface damage due to a harsh, abrasive cleaning 93|N-3 Planchet Flaw - Metal impurity or defect in the planchet – depends on severity 94|N-4 Altered Surface - Whizzed, harsh cleaning, thumbed over (using a pasty substance to cover defects or alter the appearance). 95|N-5 Scratch - depends on the severity of the scratch.
