None. A Threepence represented three Pennies in the various British based predecimal currencies. There were 240 predecimal Pennies in a predecimal Pound, so there were 80 Threepences in a predecimal Pound. At the time of Britains changeover to decimal currency in 1971, the old redundant Threepence became the equivalent of 1.25 New Pence. There are 100 New Pence in the British decimal Pound.
A Sixpence was a small predecimal British coin. Half a Sixpence was a Threepence, an even smaller predecimal British coin.
In the predecimal currency, there were 20 Shillings in One Pound. Therefore there would be 200,000 Shillings in £10,000 (predecimal).

The Penny is the basic unit of the British currency. Since decimalisation, there are 100 pence to the Pound. The decimal Penny, Two Pence, Five Pence, Ten Pence, Twenty Pence and Fifty Pence coins are still in circulation, and will be for a long time yet. The predecimal Pennies and variants such as the Halfpenny, Threepence, Sixpence along with the other predecimal currency, have been progressively demonetised since the full introduction of decimal currency in February, 1971.
A Guinea is 21 Shillings in the old predecimal British currency. There are 252 Pennies in a Guinea, therefore 504 Pennies is Two Guineas.
In the Australian predecimal currency as with the currencies of most British Commonwealth countries, it was based on the old British currency of Pounds, Shillings and Pence. The denomination of "Penny" dates back nearly 1,200 years. The "d" was a symbol used to denote Pennies and was derived from the Latin "Denarius", referring to a much earlier Roman coin. When referring to British or British Commonwealth predecimal currencies, any number followed by a lower case "d" is referring to a value in Pence, hence 10d, is Ten Pence, as it might be written on a bus ticket or a proce tag in a shop.
In predecimal currency, there were 12 Pence in a Shilling. In decimal currency, 12 Pence is 12% of a Pound (GBP).
