I have 3 mint condition (uncirculated) £10 notes. They are the ones with the single hollowgram halfway down on the left hand side. All three have misprinted hollowgrams on them, one having 1/2 prints on top and botton. They are all consec. numbers. Should I keep hold of these? I have had them for about 5 years and they are the ones that were took out of circulation when the new issue was brought in. Does anyone think they are worth more than the £10 face value?
