Margrethe II 10 Øre

While it's true that Denmark issued 10 Øre coins for decades, the version attributed to Queen Margrethe II from 1960 might not hold up, as she didn't ascend until 1972. From my experience, these bronze pieces likely featured her portrait starting around that year, continuing until the denomination's discontinuation in the late 1980s. The design was straightforward: a crowned effigy on one side, a simple wreath or value on the other, struck at the Royal Danish Mint. Mintage numbers vary by year, and some records could be incomplete due to archival losses over time.

That said, it's just a coin, not a relic from Valhalla—though I've seen collectors treat it as such.

If it existed as described, it would represent a long-running series in copper alloy, common in everyday change before inflation rendered it obsolete. We know it circulated widely, but specifics like exact composition changes remain murky without further documentation.
