This coin is in uncirculated condition but has a bit of contact wear / odd toning on the hair over the Princesses’ ear. That’s a high point, and a likely early indicator of any wear. I’d grade this between AU55 and MS61.
The obverse shows King Frederick IX of Denmark, facing to the right. The legend runs from 7:00 to 5:00 along the inside of the rim and reads “FREDERICK IX KONGE AF DANMARK” with artist’s initials at 6:00 on either side of a heart (?). The king is bareheaded, with a pronounced part visible on the right side of his head (towards the viewer).
On the reverse, Princess Anne Marie faces to the left with a pearl necklace just above the break in her bust. The legend runs clockwise from 7:00 to 5:00 and reads “PRINCESS ANNE-MARIES BRYLLUP 18*9*1964” with the denomination counterclockwise from 7:00 to 5:00 “5 Kroner”.

Other details: Princess Anne-Marie married Constantine II, the King of Greece who reigned from 1964 until the abolition of the Greek monarchy in 1973. Their reign was interrupted by the Colonel’s Coup in 1967, and he was exiled in 1967 after a failed counter-coup. After the junta fell, there was a plebiscite on 8 December 1974 which established the Third Hellenic Republic. Constantine, who was not allowed to return to Greece to campaign, accepted the results of the plebiscite and lived abroad until 2013. He was allowed only brief return visits before that (to attend funerals, open the Olympics, etc).
The couple has 5 children: Princess Alexia, born July 10th 1965 at Mon Repos, Corfu, Greece. Crown Prince Pavlos, born on May 20th 1967 at Tatoi Palace. Prince Nikolaos, born on October 1st 1969 in Rome. Princess Theodora, born on June 9th 1983 in London, who is pursuing an acting career. Prince Philippos, born on April 26th 1986 in London.
