Are these print spots or something else?

This is a WOTC base set 1st edition graded card I just bought off ebay. Trying to understand what these small white squares are on the back of the card. You can really see them when shining a light through the front of the card. Are they print spots?


These are imperfections in the plastic of the PSA case! See other discussion here:

Ah thank you!

That was one thought I had but its very deceiving whether its the card or the plastic case. Good to know that its not the card.

This has been a popular topic recently!

I’ve seen these on so many of my PSA cases and have wondered the same thing.

Cool to actually know the answer now!
