A 12-year-old boy named Heinrich Boldt discovered the entrance to a crypt containing the Curmsun Disc near a construction site in Groß Weckow, Prussia. He and his group left the gold disc inside the dark cellar for over a century before it was rediscovered.
Researchers translate the front side text as Harald Gormson king of Danes Scania Jomsborg town Aldinburg using runes from Old Norse into Medieval Latin. The name CVRMSVN translates directly to Gormson while similar coin inscriptions from York show king written as CVNVNC.
Press reports regarding this rediscovered treasure emerged on the 5th of December 2014 when Michał Sielski's great-granddaughter showed the object to her history teacher. The disc had remained hidden since Major Stefan Sielski took it home during the chaos of war in 1945.
Danish anthropologist Karen Schousboe stated in 2021 that the object was authentic based on research by Sven Rosborn but historians Wojtek Jezierski and others argue its age is impossible to estimate. Numismatist Mateusz Bogucki believes the disc is a counterfeit made by antiquity enthusiasts in the 18th or 19th centuries while no publications have proven the Curmsun disc genuine as of 2022 according to archeologist Wojciech Filipowiak.
Electron microscopic analysis at Lund University in Sweden showed a non-homogeneous alloy with gold content ranging between 83.3 and 92.8 percent. Surface and alloy characteristics matched typical artifacts from the latest part of the Early Middle Ages with no traces of modern processes or chemicals appearing during testing.
