Nobody where I come from said 'thruppence', that's just for Southern Poofters. It was, and always shall be, 'threppence'.
And a quid was a Bar, so ten bob was 'Afe a Bar.
Five bob was a dollar. Two and six was either 'Afe a dollar or two-and-a-kick. Sixpence was a Tanner.

Ah, life was so much simpler in the Good Old Days! :-)
