1936 DDO, 1941 DDO, 1980 DDO and 1968-D DDR would have to be my best Doubled Die finds over the last 8 years roll searching.
Last summer I hit a loaded box ended up with I think 8.5-9 rolls of wheats of them less then 3 were 40's 50's. nothing pre 30's were great other than 4-5 au/unc comonish teens.
1880 IHC was my oldest find in a roll. Most often $20 gets me 4-5 wheat pennies these days. Mostly 40s and 50s
My friend got a 1884 a week ago....from my bank . Oldest I got this year was a 1909 LMC. Still a nice find considering the 1916s was in the same roll.
