BRITISH GUIANA. Government of British Guiana. 1 Dollar, 1920-24. P-1A. PMG Very Good 10. Printed by TDLR. PMG has encapsulated just 5 examples of this pick variety, which is a testament to its rarity. This example is found with the early January 1st, 1920 date. Scarce, and a note which is surely missing from most Commonwealth collections. From the Don Allen Collection.
