I posted this coin/holder on the CU forum and the thread got shut down because of all the "bad blood" between many forum members and ACG (due to past lawsuits filed by ACG against certain people and organizations for defamation, ACG lost and went bankrupt, pretty much end of story). A few of the members couldn't stay on topic and wanted to rehash old arguments and began doing some ACG bashing and making personal attacks.
In any event, in spite of the nastiness, I did receive some interesting information on the history of this holder:
This was a late 80s generation of their slab. They tried inventing a new grading scale with more dimensions than the prevailing one. They weren't taken seriously for reasons that are beyond the scope of a response to your question. PCI had competing slabs with photos in them at the same time. This may have actually been a response to that, as I believe Accugrade had slabs without photos that predate this one. The coin as holdered is only of interest to collectors of TPGania (or is it TPGilia?). and:
ACG has made at least 26 versions of their slab, but the image you shared is of their first version. They opened for business in 1984 and by 1985 this slab style had been changed. PCGS paid ACG a licensing fee starting in 1989 that directly led to the halt of business at ACG. The fees were paid until late 1997 and, when they ended, ACG came back into business with their small slab style.
So, without getting into anything negative about ACG, I'm just wondering if any of you have any thoughts on this old holder? It's not mine, it belongs to a friend of mine who just wanted some more information on it before he decided whether to sell it. Thanks!
