Just felt like pointing out there's no such thing as a one pound note. There used to be, but there hasn't been for a long time. It's always coins now.
Um, GBP (British pounds) does not equal one ounce of sterling silver. Hasn't in about a million years. Silver is about $26 today and the GBP is about 1.60. Everyone in the world would be buying GBP if it had anything to do with silver.
