I have a decent collection of nickels ranging from '38 to '45, but i don't give anything newer than '45 a second glance. I've looked into key dates and nothing after '45 seems like a big deal.
The 1950 D is the Key coin for the Jefferson Series, especially on a CRH event. But there are other low mintage dates post-1945 worth keeping, especially if they are found in a high grade. But to each their own. No judgment here.
Still need a few. But getting there. Haven't bought a Jefferson Nickel yet. I have to go through all My AU/BU to update the album. Its gonna be marked as a True CRH. Album.
I have two or three Jefferson Series sets from circulation. Then I have my BU set. Many of the BU coins are from CRH too. It's a fun series to hunt, so don't give up...complete the circulation set!! You'll be glad you did!
