Denmark never adopted the euro. The 2002 referendum — the second such vote, following the 2000 rejection — kept the krone intact, making any Danish euro trial pieces a bureaucratic artifact rather than a prelude to actual issuance. These probe and essai pieces were struck as part of the standard pre-adoption technical testing process that candidate and evaluating nations participated in, but for Denmark they went no further. No Danish euro coins entered circulation, and none were ever intended to following the referendum result.
