I agree with paddyman on the 1980. Often, doubling this close is machine doubling, but the doubling on "Liberty" is showing clear, so it is definitely a DDO. Nice find!
Thanks for Posting the Doubled Die And Cud Error immediately. I keep forgetting about Newbies on Cointalk.
Nice Cud on the 1983 cent, we find a number of them for that year. Lincoln Cent Cuds; 1983 : Cuds on Coins (cuds-on-coins.com)
Nice DDO, Larry! I've been looking for that one for a long time. That's the first one I've seen posted in any forum either.
