It’s easy to know what evidence to fabricate to create provenance, but the hard part is copying the nuance in the original product, and the details to make that provenance convincing for experts. However, a fake is made for amateurs (sorry to be blunt), and is not designed to fool experts, but then, they aren’t the target (at least they shouldn’t be).
This is why it’s critical to admit to yourself the level of your own expertise. Don’t go buying cards you don’t know well because you open yourself up to these sorts of scams. I did not know enough to know it was fake. (Still, I could tell the photo was fake.) But I would not have touched it with a 391/2 foot pole because I knew I didn’t know enough to know.
