In the city, bankers are making money off money the whole time.

The same thing is happening in Bromley but in a slightly different way.

A coin collector is selling a large collection of coins for £850 despite them having a face value of just £262.

The seller claims the collection's value is "well in excess of £1,000" because the £5, £2, £1 and 50p coins are "very rare".

Coins of note include a £5 coin in memory of Princess Diana, a 50p Battle of Britain coin and a £2 First World War boat coin.
