Probably not too much more, if at all. There are still tons of them in circulation and last I checked, they're still being printed. I have a bunch of them, but I also love collecting foreign currency and more rare US currency.
Maybe a long time from now, they'll be worth more, but not anywhere in the near future. I still have a bunch of regular Kennedy half dollar coins, even though those seem even more rare than 2s, they're still only worth face value.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
