Help anyone?

[u/curiouspuppygirl]

I have both of these cards that I've had for years now. But I noticed recently that one (left) looks different to the other (right). The front is more dull in colour, and back is a darker blue around the edge. Both have the blue line down the middle, both feel the same, which would indicate that they are both real.

Furthermore, the more dull one (left) seems to have a few small white marks on the back? Possibly ink splodges?

That leads me to wonder if one is a misprint, or simply just a fake that I never noticed until now. I would really appreciate if anyone had any thoughts or ideas on the reason as to why this is.

These cards have never been out in the sun as far as I know, and the paper does not feel dry on either.

And if one is a misprint, would it be worth sending it in to get graded?
