East Caribbean States / Anguilla ND (1988) P-19u PMG Gem UNC 66 EPQ 20 Dollars
The East Caribbean States series is filled with varieties that are extremely difficult to find, and this is one of them. This is the 1988 issue with U suffix, indicating that it was initially released on the island of Anguilla. A survey of available auction records indicate just a single offering of this variety at public auction in the past decade, and that was back in 2015. The PMG population report lists just three examples of this variety, of which this is tied for the finest. An important opportunity for the specialist, not to be missed.
