a quick lunch time rummage through a table of coins at a carboot sale. the man selling them (obviously a coin collector) was a little bewildered at my choice. "you've gone for all the mouldy ones! had i known i would 'ave brought a whole box of mouldy ones. got one at home....... was gonna chuck 'em out. my wife likes the shiny ones". and she nods in agreement by his side.
