The year 1855 was a landmark year for the Swedish state in terms of reform. After the death of the conservative King Carl Johan Bernadotte, power gradually began to liberalize. Changes have come in many areas of Swedish life, including financial.
It was in the 55th that a reform was carried out, involving the introduction of a new, decimal monetary system. It was significantly different from the previous one, where the main units were Riksdalers with a very complex division into 'specie', 'banko ' and'riksgeld'. Now a new exchange unit was introduced into circulation - the era, which replaced the skilling.
Along with the innovations in the financial sector, the changes also affected the post office. In 1855, Sweden issued the first postage stamps in its history in five denominations: starting with 3 and ending with 24 skilling banco. Each was characterized by its own color, and their cost was calculated by the usual Swedish change money. The stamps were decorated with the Swedish coat of arms by Count P. A. Spare.
Then begins the most incredible and mysterious story, thanks to which the brand 'yellow trehskillingovik' was born. The fact is that the eight-shilling copies were issued in yellow, and the three-shilling ones were in green color.
