Why is sand not as valuable as gold? Sand is more common. On machine damaged examples this happens a lot. A very large percentage of these are from normal dies, but it happens on doubled dies as well. So it is a common to find these on raised devices and incuse devices. Variety collectors view them as a damaged coin. Some collect these, but set them aside in a roll and set a doubled die coins in a different roll, then soon you will see how common they are. Some sell them, but I won't because I know what they are.
