Royal cypher

Uncommon card · No. 187666

In modern heraldry, a royal cypher is a monogram or monogram-like device of a country's reigning sovereign, typically consisting of the initials of the monarch's name and title, sometimes interwoven and often surmounted by a crown. Such a cypher as used by an emperor or empress is called an imperial cypher. Royal cyphers appear on some government buildings, are impressed upon royal and state documents, and are used by governmental departments. They may also appear on other governmental structures built under a particular ruler.
