Where there any misprints on the 2000 Indian guide dollar coins?

Answer 1

There aren't any major errors known other than those normally expected during standard coin production, e.g. off-center strikes, clipped planchets, flipovers, etc.

However there are a number of different varieties of the coin including some early strikes included in Cheerios cereal boxes as promotions. These were later found to have used a different reverse die that showed more strongly-defined feathers on the eagle's tail, along with a raised shaft on the central feather. This variety sells for about $150.

Finally, to clear up some things in your question:

> They're normally called Sacagawea dollars because that's the name of the Native American woman depicted on the front of the coin.

> Coins are said to be struck or minted; dollar bills are printed. So the term for an error is a mis-strike rather than "misprint"
