Valuable? Hastings 1066 FDC? Have just posted a link to a UK FDC from 1966 with one stamp from the series of Battle of Hastings stamps. The FDC in itself is of little value, but the fact that the original letter is inside and was sent to a child telling that this FDC might be valuable one day adds to the value. The letter inside the envelope often adds much value to a simple postal cover of FDC.
