Scotland, Royal Bank 1.5.1981 P-339 PMG Gem UNC 66 EPQ 20 Pounds
Very scarce note from the Royal Bank dated 1981. At the time this was issued 20 Pounds represented quite a bit of money in Scotland, and relatively few of these were put aside by collectors at the time of issue. This one is surpassed by just a single example in the PMG population report.
