Base set Charizard Dot error?

I’ve seen this a handful of times but I never really found any information as to how it happened or if its more/less rare than other errors. There’s a ink dot in between the word Nintendo. If anyone has info i would really appreciate it. Thank you in advance!

Yeah, that’s pretty ugly. It could hurt the grade. Avoid

I found this album posted on Reddit and it really peaked my interest. So I’m here wondering if anyone had info on it. But I do appreciate the look out haha.
