Good point about collectors posting such pics in auction listings. If collectors and dealers took photos of this quality, authentication could be done via email. I've often told collectors that if they send me close enough photos-- including high-quality scans-- I can tell them in the card or photo is authentic. And some do.
10x loupe versus 60x microscope versus 250 digital microscopes. They're all so cheap, you can buy all. And, as I said, a high-quality scanner can produce big/detailed enough images.
