It's fun (and sometimes aggravating) to look at old price books. I've got a 1990 Whitman Handbook of dealer buying prices. Makes me wish I'd bought more rare coins 26 years ago!
I got my copy from the Goodwill Thrift Store I got it signed too! It seemed that the Author was doing a book signing at the Goodwill before he was flipping an arrow sign in front of H & R Block.
Of course it's now 7:31 PM est. He's had is milk and cookies and got his jammies on and tucked In by now!
