Nickels have been the “red-headed stepchild” of US numismatics until recently. This may explain why so many errors, such as die breaks and cuds have been found the past few years. I noticed this several years ago, and until my health took a downturn recently, I would search between 4 and 20 boxes of nicks a month. Plus other coins, of course.
Results were fairly consistent. 20-30 keepers per box. This includes all errors, key dates, older AU, Buffs, War, “V”, and anything else of interest to those on my potential buyers list.
Time for more coffee.
