My sentiments exactly. This is nothing but a money grab, as no doubt there are fees involved to support this "service". I too have identified countless counterfeits on the eBay platform over the years and have always been ignored. I'd estimate (20) separate reports of counterfeit 1927 Albania 5 Franga Ar Provas alone. Not once have they ever taken action.
eBay is rampant with photoshopped coin illustrations. Tenth ounce Gold American Eagles in a slab altered to make the coin look the size of a one ounce coin etc. If they can't even police obvious photo doctoring on the site, what's the point in physically inspecting anything?
It's like most bureaucratic decisions: attempt to solve an issue but avoid some of the easy solutions. eBay had an employee that would review listings a decade or more ago (with the help of collectors who would report fakes) and that would be a simple first step to remove a large number of the obvious problematic listings. This authentication program is a good idea but it would work better if it was targeted to a smaller group of items where a picture is not enough to verify the coin.
Yes lots should not be eligible but for some reason the system is not recognizing that as I saw someone on the PCGS forum who also had a lot of junk Kennedy Halfs go to the authenticator and then get the same reply of it not qualifying for the program. Maybe sellers need to select an option on their listing to indicate something is a lot but plenty of listings could have carried over from before the program started and it's probably not an obvious setting (where the seller clearly sees they need to choose lot or single coin).
