"Skullcrusher" Henderson (played by Nick Scott) is the most prolific currency forger in London, although this is more down to his tendency to crush the skulls of any rivals than the quality of his forgeries (which feature Danny La Rue in place of the Queen).

Richie and Eddie fell afoul of Skullcrusher and had to pay a £5,000 tribute in order to escape bodily harm; unfortunately they tried to pay Skullcrusher with his own forged cash, and got their skulls crushed anyway. Appeared in Dough.
