I believe these are DDO? I’ve done my research just not positive if they are DDO or MD or another error. There is Multiple cents
Just a suggestion, I think you will generate more interest this way. Having pics of one coin at a time to include entire coin in the image of obverse, reverse, and if able to maybe include a close up view also. + 1....There are some DD's known for the 83 ie my reply. Believe I read the 83 had e pluribus unum DD found. Keep your fingers crossed.
All 1982 quarters are DDO. The master die was doubled for that year. Can't speak for the 83's though.
