I have one of these. Well, I didn't know I had one until I found it in the back of a drawer. I couldn't figure out where it came form or why I had it...sounds pretty organized right? Anyway, does anyone know what 'company' or whatever might have produced these. Mine is also a 1981. Could it have been some kind of promo that Littleton may have done? I bought coins from them when I was a kid and I wonder if that is where this is from.
