I'm not sure this piece would catch so much more in Scandinavia, I'd almost wager the opposite - that this could be a very common find in junk lots, particularly exclusively Danish coin lots that are of rather low interest in a region where they're still littering jars and drawers. While this is an impressive piece, its historical context needs to be considered. It was issued just after the seemingly global abolishment or debasement of silver as Denmark had in circulation until these pieces were issued in the 1920's. Because they are base metal, they would have circulated for longer (up until the 1960's) when the last large 2kr piece was issued. Like in neighbouring Sweden (and comparable to US/Canadian 50c pieces), these large coins would have been seen as large, bulky and a relic of the past and tucked away, meaning many circulated pieces are readily available today.
One fun fact about this piece is that while it would be rather difficult to spend, it is legal tender for 2 Danish Kroner. The National Bank keeps any
issue of a denomination legal tender until it is demonetised (eg. the 25 ěre pieces in 2008 - in which all previous issues could have been used up until then). This means that despite material and size are woefully incorrect, you could use this piece to pay off your debt of DKK 2, but that would barely buy you a grain of rice in Denmark
