I can’t pull them up at all. Even their Facebook page is not found. I know a few threads on this TPG exist but they are older. I just happen to have these 3 coins graded by them. Not sure where I got them but the quality of the coins does not come close to the grade from my point of view. I know I didn’t pay much for them, definitely less than $5.00 but I wanted the dates and mint marks, all 2017 with P, D and S. The S is the nicest looking of all.
According to a post from @Conder101 they have been around since 2009. This is a basement slab like @Lon Chaney mentioned (although one can argue it is a bit above that since they technically had a website that took submissions-so it was not just slabbing their own inventory like basement slabs normally do). The wayback machine shows that the website has been "Under Construction" for several years. 2020 appears to be the last year that it was working and advertised taking submissions. Around 2021 is when it went to the "Under Construction" message.
You can tell that their inner liners are “inert” by the spots and toning. Did anyone else notice the 2017-P cent was the 225 anniversary of the cent? It’s even a “One Year Issue!” WOW! How could I have missed it?
