Over the years the 'Gibbons Commonwealth' catalogue has seen many changes. This is the second edition since Gibbons compacted its listings to cover the era of pounds, shillings and pence up to the end of 1970. (This is fair as the currency in Britain and various other territories goes, though Canada and her territories went decimal in the mid-nineteenth century). This boundary is extended in a few instances, such as the Barbuda British monarchs series, issued at regular intervals over an eighteen-month period spanning 1970-1, but by and large this is what we might call the sterling era catalogue.
