just fishing for a sucker is all this seller is doing and there are many suckers who will fall for this
There are several similar coins listed by the same seller. They are described as "potential errors". Would anyone really buy a potential error?
I'm thinking that the shipping cost on that listing isn't the only thing she's set at 4.20, if you know what I mean.
I think the noun she is searching for is "Nutcase." nutcase | ˈnətkās | (also nut case) noun informal a crazy or foolish person.
It was specifically calling out "Skip at ICG". Not that I understand how she'd expect him to see it, since according to her he's obviously blind as a bat...
