Oops... you guys are right, its 20 billion and not 200 billion, messed up.
Ok so if my math is right (and I could be wrong) and I use the convertion chart Jan-Poo provided then the converted amount for Octobrt 1986 comed out to be $123,877,361.41. Wow thats quite a bit of money for someone rich back in that day. Its probably worth more in today's world. Well even if I am wrong I think thats a pretty accurate answer to go by... thank you all for the help.
