How much is a Shilling worth in Australian Dollars in the 18th century?

Answer 1

The first Australian Shilling was minted in 1910.

Prior to that, the colonies that were to become Australia, and for a few years after Federation, used the British currency.

There were 12 Pennies in a Shilling and 20 Shillings in a Pound. At the time of Australia's conversion to decimal currency in 1966, the Australian Shilling converted to 10 cents.

One British Shilling in 1800 had the purchasing power of about $4.20 AUD today.

One British Shilling in 1900 had the purchasing power of about $6.26 AUD today.

NOTE - This historical conversion is the result of many calculations and considerations for which I cannot take credit. The resulting answer should only be regarded as an approximation.
