Even in low mint state grades, they are only with a few bucks. Jefferson Nickels are really only collectible in gem grade or better. The only notable exceptions would be 39-D, 50-D, war Nickels, and the major varieties.
@idhair is right very little resale value but they would sell retail for a few dollars for the lot. BUT they are perfect for a simple folder to store and display. Keep on searching! Reed
Your easiest find with Jefferson Nickels is War Nickels which are coins from 1942-45 with a large mint mark over the dome of Monticello. One of the key varieties to look out for is the 1939 Rev of 40 DDR “Doubled Monticello”. The doubling is dramatic enough that it is still easily identifiable in the circulated grades (see photo below). Happy hunting!
With regards the Jefferson Nickel Series, it's probably the only series that a complete collection can still be built. From pocket change and CRH events, you should be able to put together an AU/BU grade collection from the 50s through present. And you should be able to find many XF/AU/BU Jeffersons from before then (many liberated from another collectors collection by family usually after the collector dies). Patience, time, and volume is all you need. So start to set aside those dates/mms and work the system for the best you can find to fill up an album. Good luck...and have fun!
