At the moment the best investment paper in the UK can be found in the shape of Royal Mail stamps. I'm not talking about philately type of rare stamps, but the routine day to day 1st and 2nd mail letter post stamps. Not the ones with an actual value in pence, but the ones which actually state "1st" or "2nd" class. Their value has increased way above the rate of inflation over the past few years. Now I hear the Royal Mail has the agreement from Ofcom to put up the price of 2nd class stamps by a further 50% in a few weeks time.
