I remember hearing of a story of a US coin being graded and signed by the artist because it contained an error. The artist was given a large number of them and it turned out the ones the artist received were rare because it had some sort of peculiar error..
Does anyone know what coin I am referring to? Its driving me nuts.
Are you talking about the Goodacre Sacagawea dollars? She was paid $5000 in Sacagawea dollars that had a special finish. But the error coins were the cheerio Sacagawea with detailed tail feathers. The Goodacre coins just had a special finish, they weren't errors. I believe the majority of the Goodacre coins were graded and identified as a special finish.
