Authentic T205 Cy Young?

[grandcards]

Hello all:

I picked up this T205 Cy Young off of eBay thinking that it looked good enough to me, but would love another set of eyes. I am not a long time collector, but have a few T205s to compare to and have a pretty good feel.


However, there was one aspect of this card that causes me concern.

Here is a link to an album of images, that includes a short video at the end. https://photos.app.goo.gl/4N27T2C2d9aXHNGd9

In the video you can see that portions of the border "shine" under a light, in a way that I haven't seen before. I have looked at it over and over and think it must be some sort of foreign material that reflects differently (it does not light up under UV), but I can't figure it out and it is not obviously visible.

Other aspects of the card seem fine for verifying authenticity: Print pattern seems good; borders, though worn/tarnished, look ok; PB back shows PB-style staning; chipping and creases look consistent with authentic copies; Background is a "speckled" red and not solid, but a quick search of the PSA registry shows a number of similar backgrounds that have been graded.

All in all, I think I'm good, but would love a 2nd opinion just in case while I'm still in the 3-day return window!
