Here are some examples of marble "errors" known as micro peewees. Once again, these very tiny marbles were found only in the old dumps. The smallest ones I have found are just about 1/4 to 5/16 of an inch in diameter. I put a regular 5/8" marble in the pic to give an idea of how small they are. Some of the micro's can have some decent value to them.
