The coins currently in circulation in Britain are for 1p, 2p, 5p, 10p, 20p, 50p, 100p and 200p. When I gave one of each of these coins to Tom and Harry to share between them, each took two or more coins, with each person's coins' total value equal to a prime number of pence. No coins were left over.
I asked Harry whether his share was a specific number of coins that I mentioned. He said "no".
I then asked Harry whether he had the coin of a denomination I specified. He said "yes".
His two answers allowed me to determine the total of the value that Harry had taken. What was that value?
