Minted between 1873 and 1931, Danish 20 Kroner gold coins featured three different rulers: Christian IX, Frederick VIII (Shown), and Christian X. variety. All Danish 20 Kroner coins have a Mint Mark that is heart-shaped, signifying the Copenhagen Mint. Kroners were often also struck with one to three initials signifying the Mintmaster or Moneyer. The Krone was an official unit of Denmark's economic system, the present form being introduced in 1874, one year after the kingdom abandoned its silver standard.
The obverse features the bust of the ruler with the name of the country ('DANMARKS ' KONGE' or 'KONGE AF DANMARK') surrounding the ruler. The date also appears on the Christian IX and XI versions. The reverse of the Christian IX and Frederik VIII versions of the coin are nearly identical. The date, denomination, and any minting marks sit below the coat of arms of the kingdom. The Christian IX reverse features a design commonly referred to as a Mermaid, a design that depicts Liberty sitting on or next to a bundle of wheat, holding a staff and a shield. The tail of the herring at her feet seems to blend into her legs, giving the illusion of a mermaid.
