In September 2016 Ebay seller relicsrecycled from Plymouth, Pennsylvania, USA was trying to sell this fake Denmark plate.
It has the wrong dies and an impossible registration. I am sure the seller is just a dealer of anything and everything so he cannot be expected to know this is a fake.
Although it looks like it could be genuine, always check that a plate is close to that particular country’s genuine plates. There are several websites like Francoplaque and Plateshack that have pictures of genuine plates.
