Problem is, especially with T and N cards, there is so much legit variance that I don't know what parameters you could use to detect illegitimate variance. There are trimmed cards that measure correctly and legit cards that measure small etc.

Well that's partly why I'm starting w Goudey as there are somewhat easier
markers - but also - you can see if a card has recently been cut under magnification so t cards could work though it would be harder. I also am aware that this is not an original idea - I just happen to have a CV-MV test harness laying around so its a fairly manageable project.

Trust me I'm behind you 100%!

I think that this would be an excellent project.

Do you think it would be able to detect whether a card is fake or altered while it is still sitting in the slab? We can then determine which grading companies have been doing a good job.

Excellent! News I've been hoping to hear.

Do you think this would be just a 2D scan of the front and back? I would think if you could also look at the edges and surface of the card (in a three dimensional way), that would provide additional information.

There may not be one single marker that points to either 'altered' or 'fake', but taking in several bits of information can point you in that direction.

For example if a card has been flattened and then trimmed, I could imagine that you could look at the edges under high magnification and see the results of that recent cut and also look at the surface and see that it has been flattened.

Good luck and may the force be with you - I watched The Last Jedi again tonight and have tix for Rise of Skywalker tomorrow.

Careful though - PSA might buy you out and then bury the technology.

I've been hoping someone would step up and create something like this. I figured we just needed someone with the right equipment and expertise to come forward and make it happen. I'm certainly behind you 100 percent.

Focus on authentication, skip grading.
