Misprint ninetales

[Hatch11]

l have a ninetales with what l believe is a misprint . Right beside the blue weakness symbol there’s also a yellow circle with red marking inside . Has anyone ever seen this before ? Just trying to figure out if it’s worth anything . Im trying to figure out how to post pictures
Thanks in advance for any help

Yes that is a misprint, but not necessarily the kind that adds value.
Blemishes often detract from value.
Saying that, there are some blemishes that add to value.
It seems to be based on how interesting it is.
That one is actually moderately interesting, since it is similar to the Weakness symbol that it is next to.
A collector of misprints might give you a higher value.
Maybe two or three times what it would normally go for.
