The British Shilling and the Shillings of most other Commonwealth countries are part of long redundant currencies which no longer have exchange rates with any other currency.

Ten Shillings converted to 50 New Pence. 10 British Shillings in 1971 had the purchasing power of about £4.73 GBP today. 10 British Shillings in 1971 had the purchasing power of about $7.60 USD today.

Britain used Pounds, Shillings and Pence as their currency for many years. There were 12 Pence to the Shilling and 20 Shillings to the Pound. Many British Colonies and countries of the British Empire/Commonwealth also used Pounds, Shillings and Pence.
With the possible exception of traders tokens (with the traders business name on them), there were no "New Zealand" Shillings minted prior to 1933. Any Shillings circulating in New Zealand prior to 1933 would have been mostly British Shillings and some Australian Shillings.
A Halfcrown is the eqivalent of Two Shillings and Sixpence. A Crown was Five Shillings.
There were no British 1952 Florins (Two Shillings) minted due to there being sufficient coins already in circulation. Two considerations that may have influenced the non-issue of a 1952 Florin were that from 1919 to 1946, all British "silver" coins had a silver content of 50% and there was a rush to get them out of circulation, so relatively large quantities of cupro-nickel coins were minted from 1947 to 1951. From 1947, all British "silver" coins were made from cupro-nickel. The other less likely possibility is that King George VI died in February 1952 and any coins that may already have been minted, were not subsequently issued.
It depends on which currency you are using. In British coinage there were 20 shillings to the pound. Do the maths
In British currency, the value of a shilling in 1830 was equivalent to 12 pence. Therefore, a pension of 30 shillings would be calculated as follows: 30 shillings * 12 pence/shilling = 360 pence. So, a pension of 30 shillings in British currency from 1830 would be equivalent to 360 pence.
There were 20 Shillings in the British Pound every year, including 1910.
