Swedish coat of arms definitive stamps

Swedish coat of arms definitive stamps were issued by the Swedish mail service, Posten, beginning with the country's first adhesive postage stamps on 1 July 1855. These initial issues featured the Swedish coat of arms and were denominated in skilling banco across a set of five values. They marked the introduction of perforated stamps to Sweden and established the standard of bearing the country inscription 'SVERIGE', a feature continued on all subsequent Swedish postal issues.

Following a change in national currency to öre and riksdaler on 1 July 1858, a new issue of stamps was required. The postal authorities retained the coat of arms design from the 1855 release for this updated series, though the stamps were manufactured in a slightly smaller size. The arms stamps functioned as the standard definitive issues before being replaced by newer designs, including a reclining lion motif introduced for selected values in 1862 and a large numeral design introduced in 1872. Later, in 1910, the Swedish postal administration revived an arms design for the lower denominations of a new definitive series that also included portraits of King Gustav V.

In terms of physical design, the stamps are perforated and centre on the Swedish coat of arms, framed by traditional borders and clearly inscribed 'SVERIGE'. The earliest 1855 release comprised five values, with one notable printing error resulting in the Treskilling Yellow. While the 1858 issue preserved the visual appearance of the arms from the 1855 release, it can be separated by its slightly smaller physical dimensions and its currency denominations in öre. Decades later, the 1910 series incorporated an arms design exclusively on low values, distinguishing them from higher denominations depicting the monarch.
