In Victorian London, what was a tosher’s job?

am surprised that they haven't made a film about it!! can't think what we'd call it tho?

hmm, nice work if you can get it!!

Tosh is an old cockney expression used like 'mate'. Also does anyone remember Tosher the Tie King of Petticoat Lane market. He was a street seller of ties with a loud booming voice and always had a large crowd listening to his nonstop banter.
