Old Clay Marbles - Blues and Purples

I'm not over my obsession with old clay marbles in all their variations, and am adding a few new sets of what I believe are quite old ones. This batch includes at least a couple of Benningtons, as well as some that are very mottled--or marbled!--in color. So pretty. 

About 50 marbles--exactly as shown. These average about 1/2" in diameter, some a little bigger, some a little smaller. I've tried to weed out any with much damage, but certainly there are a few little chips here and there.
