Well Im going to pop in here and say I don't work for anyone. I am retired and just wanted to help out a few folks that might be in need. Also most everyone is saying the 50s are worthless. Well that is correct if your talking todays value but say you have a 100,000 in 50s and it rvs at 10 cents or a dollar. How worthless are they then. I exchanged mine for that very reason. Exchange yours if you want, throw em in the trash if you want or give them to me before the deadline and I will build upon my stash. Just trying to help folks. This is one of the reasons I never post, always somebody to trying to make you look bad.
