Northern Ireland, Northern Bank 1.7.1970 P-190a PMG Gem UNC 65 EPQ 20 Pounds
A very difficult date in this series from the Northern Bank. This is the first date of the type, which was printed in very small numbers, although later dates are not exactly common either. A survey of auction results show no offerings of this date at public auction in recent years.
