How the international records were verified
The Kiribati, Bahamas and Nauru entries were checked in the Universal Postal Union-supported WADP Numbering System. WNS participation is not universal, so absence from that database does not prove that another postal administration never issued a related stamp.
Postal-use boundary
Foreign issues are not valid USPS postage. Current validity must be checked with the issuing administration. Denominations, current postal validity and collectible value are separate questions; this table does not establish rarity or resale value.
