Good morning. Below are pictures of what I believe is a 1972 DDO (see the large version). Using coppercoins.com, I am including what I believe is the marker also. Please let me know if you agree or not and where I am going wrong. I value all your advise as I keep trying to learn all this. Remember, I am a rookie, so go easy on me if I am way off base :smile. Thank you. :smile
Sorry, I can't make your day. I don't see any doubling in any of your pics. But keep looking, if you look enough you'll be rewarded!
The ones that seems possible to me is die #5( CONECA)( WDDO-010) . But the photos aren't good enough to see the markers given by Wexler and Flynn. Also according to them about 1/2 of all 1972 P,D,S coins were made from doubled master die, so they would be very common and no additional value. I just can't see enough details to differentiate. Jim
