OK I know I see things that aren't there but I believe this doubling is real. besides the usual plating issues. I see rounded edges on the doubling instead of shelf like every other "DDO" I've found ... lol
I see plating problems and lighting issues. Not a doubled die. Have you compared your coins to ones found on coppercoins.com? It is importsnt to learn the characteristics of a doubled die compared to worthless forms of doubling. It may help you answer a lot of questions yourself.
There are what 7 types of doubling? Some are very subtle and are visible as thickening of letters and or notching the tips of the letters. They won't all look like a 1983 ddr or a 1969 ddo. I have an 83 with very thick 8 and 3 that u said wasn't doubled but on Coppercoins.com they show it.
I am well aware of the very subtle doubled dies, and the different classes of doubling. My opinions of coins are based on what I see from the pictures you post. In my opinion, from the pictures provided, this coin is not a doubled die.
I believe you as well. It's usually one of the last ones I look at before bed. I have so many doubled dies that have everything but the doubled part. Lol
