How rare are these?

I've seen this one pop up often, and I'm thinking of making an offer. I'm not sure how many exist, or how common this error is overall.

I didn't even know these errors existed...I'm going to have to go through my old binder of 1990 Score...

dude's smoking crack - he's had a pair of Butlers that he's been listing for at least 6 months. I've never seen any others, but since he's never wavered from $35, he can sit on them forever. I'd pay maybe $5 for the set, but won't lose any sleep over not having them.
