But that's because where I live in a Mojave Desert ghost town that's the kind of marbles found here. Please understand that Trona,Ca is is at the End of the World. There's a sign outside town 'HELL 10 MILES..TRONA 15'. I think that travelling marble salesmen were hard-put to reach Trona back in the old days. It's 130F here in summer,8F in winter with hurricane force sandstorms. So when a kid got a bag of marbles to play with it was a big deal. I know an elderly woman here who at age six played with live rattlesnakes. I don't think many horse drawn carriages or Model T Fords reached Trona. I'm saying the selection of dug marbles I've accumulated are mostly Akro Agate and Ravenswood. This because Akro and Ravenswood salemen must've really needed the money more than salesmen from other marble companies. Who else would pass thru Hell with a briefcase full of marbles to snag a sale from a kid?
