This one is going up for auction at the Orlando Fun in January. Imagine finding one of these in your change. What do you think it will sell for? https://coins.ha.com/itm/errors/191...y-BuyNowFromOwner-MostActive-Thumbnail-112917
If you click on the Heritage auction link and scroll down it gives you a little history surrounding the coin.
In the write up it says that it is unknown if it was a pattern coin or not. There are 6 Indian head cents known that were struck on quarter eagle planchets. DR. Judd had attributed 2 of them as patterns. But the latest edition has them categorized as mint errors.
