Answer 3

British predecimal coins have been produced for well over a thousand years. For that level of detail, you really need to consult a coin catalogue.

Even since the Great Recoinage Act of 1816, there have been significant variations in the dimensions and composition of British predecimal coins.

Since we do not have unlimited space, I will deal with the British predecimal coins of Queen Elizabeth II (1953 to 1970).

Farthing - Bronze, 20 mm in diameter, weight = 2 .852 grams

Halfpenny - Bronze, 26 mm in diameter, weight = 5 .658 grams

Penny - Bronze, 30.81 mm in diameter, weight = 9.396 grams

Threepence - Nickel-brass (dodecagonal), 21 mm in diameter, weight = 6.8 grams

Sixpence - Cupro-nickel, 19 mm in diameter, weight = 2 .83 grams

Shilling - Cupro-nickel, 23.6 mm in diameter, weight = 5.63 grams

Florin - Cupro-nickel, 28.5 mm in diameter, weight = 11.5 grams

Halfcrown - Cupro-nickel, 32 mm in diameter, weight = 14.2 grams

Crown - Cupro-nickel, 38.6 mm in diameter, weight = 28.2 grams

Since the Great Recoinage Act of 1816, the "Sovereign" coinage has maintained a fixed standard -

Half-Sovereign - 22 carat Gold (91.67%), 19.3 mm in diameter, weight = 3.99 grams

Sovereign - 22 carat Gold (91.67%), 22.05 mm in diameter, weight = 7.9881 grams

Since the Great Recoinage Act of 1816, the "Maundy" coinage has maintained a fixed standard, except for 1911 to 1946 when the coins were made from 50% silver -

Penny - Sterling silver (92.5%), 11 mm in diameter, weight = 0.417 grams

Twopence - Sterling silver (92.5%), 13 mm in diameter, weight = 0.9426 grams

Threepence - Sterling silver (92.5%), 16 mm in diameter, weight = 1.4138 grams

Fourpence - Sterling silver (92.5%), 18 mm in diameter, weight = 1.8851 grams

Answer 5

The 1787 British Sixpence was the first Sixpence minted since 1758 and the last minted until 1816.

They were 19mm in diameter, weighed 2.827 grams and were made from .925 Fine silver.
