Did you at all edit the lighting / coloring / use flash on the card? Because by the saturation it doesn't look legit.. but that could be for a plethora of reasons.

Even after comparing it to mine at a similar angle, i wasn't able to line them up perfectly. Might just be my dumbass in photoshop, might be a sign yours is an illegitimated card.

Bottom line, I don't know. Someone smarter with text and con identification are gonna have to decide this one.

The collector's number font does look extremely off, and the card feels too dark from the photos (but that could be the lighting).

And that first edition stamp feels weird, but as I don't aggressively collect first editions that could just be my memory of the stamp itself being wonky.
