Sorry they were actually Bonds and not Stock Certificates..I should have bought one years ago when they were considerably cheaper Doug..Contact Hugh Shull in Lexington,SC.Hugh is the leading dealer in CSA paper.The same RR also issued its own small denomination currency in 1871 but with Forrest's engraved signature and not hand signed like the Bond. Their only a 1000 or so! I would speculate you could even hunt around and find an original Little Rock & Memphis RR Bond from the early 1860's.
