A friend sent me an email..saying that on the local swap shop some guy was wanted to get rid of 150+ pieces of cast iron including some Griswolds, wanted someone to make an offer. I called and left a message, I was turning flips....and bouncing off the walls, then he called me back. Said they were all cast iron ash trays, with some Griswolds. He said, he had been collecting them for 25 years or so. I wasn't really interested....so are there any value in the little cast iron ashtrays? I figure the Griswolds are worth less than $10 each, and a lot of them are advertising ashtrays.
