Thanks for the reply.I didn't realize they were so collectible.I got this one for a dollar at a yard sale.I have seen some at antique & collectible shows,most were from the 80's,anywhere from 10-20 bucks a piece.I'll have to keep an eye out from now on.Very Cool,thanks again! I gotta go detecting,it's been over a month and i'm itching to go.Maybe this weekend?Good luck to you and what's the most expensive glass listed in your book?What about the oldest one?
