I meant that current TPG's have no market incentive to do this, so why would they? Aside from the noise that has been made on Blowout and here and in a few other spots, other collectors and investors largely don't care about the alteration scandal.
Yes, APS and PF and others.
My club had a talk by an expertiser, and while most of what he talked about was stuff I knew, there were some things I had never heard of.
Like one of the 1870's-80's papers being detectable because it's ever so slightly flourescent under a blacklight.

There's an outfit that's doing some very advanced work studying stuff like color and paper scientifically.
Someday I hope Something like X-ray diffraction is available affordably enough for hobbyists.

But a blacklight usable for cards is around $10, and decent magnifiers and measuring tools can be had for well under $100 total.
Going with a really good dual range blacklight, magnifier and measuring tool would be possible for under 500.
