But I also know that the main argument (aside from wanting to hold the coins) against TPGs is that they don’t guarantee authenticity. The TPGs only guarantee the grade. I’m wondering if NGC also guaranteed authenticity would more people slab their ancients? To be clear when I say “guarantee authenticity” what I mean is that if an ancient coin in one of their legit slabs one day is proven to be fake the TPG will reimburse the owner of the coin the full market value. Just like if PCGS slabbed a counterfeit Morgan Dollar. They’d reimburse the buyer. I’ve always thought NGC should just make the same guarantee on ancient as US coins. I know the reason they don’t do it is because it’s impossible to 100% guarantee ancient coins but I haven’t heard of any NGC slabbed coins turning out to be fakes and even if a few have been that’s still like 99.99% success rate in determining authenticity. Even if they are wrong very rarely and a fake does get slabbed they would more than cover the cost from the increased revenue from more submissions due to the guarantee. Idk what do you guys think?
