Darrin, I do the same thing and now and then dig up some marbles like you did. One time i dug up a clay marble that sat right on top of a nickel that was pretty cool. I have been running a metal detector for (many) years. Keep looking and one day you may just strike it rich, as I am still looking for that myself. Chuck G---
Dave, i agree with Melissa. The last photo if you look at it, it shows red patch, yellow ribbons, red ribbons and then yellow patch, as with MK the patches will be opposite colors, but sometimes hard to tell. Chuck G---
I would agree, Jabo all the way from what i can see. I just went thru two half gallon of mostly Jabo and found some that matches, and yes, the ying-yang twist on some of them also. Chuck G---
