The UK has a similar privilege with postage stamps. They were the first to use stamps, and because of that they don't need to put the name of their country on their stamps:

"... on May 6, the Penny Black became the world's first postage stamp in use.

The stamp was originally for use only within the United Kingdom of Great Britain and Ireland and as such was in effect initially a local stamp. For this reason the name of the country was not included within the design, a situation which continued by agreement with foreign post offices, provided the sovereign's effigy appeared on the stamp. Envelopes sold with postage paid did not include this, so were marked with the country's name. In 1951, the special commemorative issue for the Festival of Britain included the name "Britain" incidentally. It could therefore be said that the name of the country then appeared for the first time on a stamp of the UK, although the word "British" had appeared on British Empire Exhibition commemorative stamps of 1924."
