Even today I don't think they've figured out a way to send items through a telegram. There are times when I think it would be nice to be able to send your money to your bank (for a small fee), but I think it's probably hard enough for most duelists to get money from players already, and it would make it almost impossible for anyone to get their money back after losing a duel if it could just be wired off to a far away bank as soon as it's stolen.
