Scott 1295B, released 2008. In 2005, 4 new values were issued to commemorate the 100th anniversary of the "wavy line" Danish stamps. The 500 ๖re wasn't among them, that value was added later. In 2010, it was released again in self-adhesive format.
My Scott, SG, Michel AND Facit all date from 2007 or 2008, which isn't new enough for this stamp. But Jay Smith lists everything Scandinavian on his site, with Scott numbers.
