Burundi's "Beermats"
These stamps depict coins of various denominations and King Mwambutsa IV.
On August 9, 1965 Burundi issued a set of eight round stamps embossed on gold foil. The stamps depicted various coins and King Mawambutsa IV. The king, whose reign began in 1915 under German and later Belgian colonial control, was deposed by his son in 1966, four years after Burundi had achieved independence.
According to James Mackay, novelty issues of this sort were refered to as "beermats" by philatelists when they were first issued by Tonga in 1963. Similar stamps were also issued by Sierra Leone, Bhutan, Qatar, Sharjah, Umm al Qiwain and Jordan within a few years (113).
