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
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.

British pre-decimal coins with no mintmark were minted at the Royal Mint London.
No. The window of opportunity for an exchange of British predecimal coins closed many years ago.
Most likely no. Most British predecimal coins are no longer legal tender. The predecimal Crown was never demonetised and is still legal tender. The decimal Halfpenny, the larger pre-1990 5 Pence, the larger pre-1991 10 Pence and the larger pre-1997 50 Pence have all been demonetised and are no longer legal tender. The Commemorative 25 Pence and Five Pound (Crown) coins are legal tender, but not intended to be circulated. All other British decimal coins should be all right to spend.
There were 240 pre-decimal pennies in a pound.
No.
In the British decimal currency, there are 100 pence in a Pound. In the British pre-decimal currency (pre-1971), there were 240 pence in a Pound.
All predecimal British coins have long since been withdrawn from circulation and demonetised. The decimal Half (New) Penny was demonetised in 1984. The larger pre-1990 5 Pence coins were withdrawn from circulation and demonetised in 1991. The larger pre-1991 10 Pence coins were withdrawn from circulation and demonetised in 1993. The larger pre-1997 50 Pence coins were withdrawn from circulation and demonetised in 1998. All other British "Pence" coins are still legal tender.
There are no British general circulation decimal coins that could be considered to have any collector value unless they are "Mint Uncirculated", "Proof", or part of a "Mint" or "Proof" coin set.
Value would be between £4- £6 as at October 2010.
All years of issue of the British decimal Twopence coins are still potentially in circulation so, unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they are worth 2 Pence.
