Definition of "tosheroon"

“’Ere y'are, the best rig-out you ever ’ad. A tosheroon [half a crown][sic] for the coat, two ’ogs for the trousers, one and a tanner for the boots, and a ’og for the cap and scarf. That's seven bob.”

1933 January 9, George Orwell [pseudonym; Eric Arthur Blair], chapter XXIX, in Down and Out in Paris and London, London: Victor Gollancz […], pages 214–215

tush or tosh. Money: Cockney: late C.19–20. Ex: tusheroon... But H. errs, I believe: he should mean half-a-crown, for tusheroon and its C.20 variant tossaroon (2s. 6d.) are manifest corruptions of Lingua Franca MADZA CAROON.

1961, Eric Partridge, The Routledge Dictionary of Historical Slang

Half-a-crown is known as an alderman, half a bull, half a tusheroon, and a madza caroon; whilst a crown piece, or five shillings, may be called either a bull, or a caroon, or a cartwheel, or a coachwheel, or a thick-un, or a tusheroon.

1859, J.C. Hotten, A Dictionary of Modern Slang, Cant, and Vulgar Words

‘Tush’, for money, would be an abbreviation of ‘tusheroon’, which in old cant, and also in tinker dialect, signified a crown.
