In pre-decimal Oz, a quid was, well a quid. Or a rug, a cracker (as in 'not a cracker' for what I haven't got), a fddley (rhyming slang fiddley-did), a flag or a toad or toadskin, or a smacker. Five quid couldabeen a spin or spinner, or a bluey or half-a-brick. Ten quid, well that was a brick, a salmon or a red 'arry and you were doing well if you had one.
Fifty smackers was a good whack when the shed cut out.
Coins: a shillin' was a bob or a deener (Riverina, Murrumbeena) sixpence a zac (Andy Mac, I'll be back) thruppence a trey, trezzie or tiddley, and yeah five bob was 'a dollar'. A penny might be a bronze or a brum, or a sunburnt twobob, a ha'penny, a mock or an oddie.
Lots of lovely moolah, plenty of spondoolicks, oodle, oscar (Oscar Asche) flush. Flash as a rat with a gold tooth. If you had a grand you could call it a winkie.
Or you could be broke to the wide, without a skerrick, having Buckley's ( a Melbourne establishment, Buckley and Nunne) or not having a brass razoo.

I may be getting carried away. Maybe I should be...
