Josh S is looking to complete his collection of commemorative Olympic 50 pence coins. These were originally issued in 2010 and 2011, in 29 different designs, each depicting a different Olympic sport.
If you have any of these coins and would like to “double your money”, Josh will pay you £1 for each coin. Or if you have an “uncirculated” coin, i.e. one that is still within its Royal Mail packaging, then he will pay £2 per coin.
You can reach Josh on 727.
