King Christian IV (1577–1648), issuer of several coins featuring the divine name יהוה (YHWH).
...Christian IV issued a remarkable series of coins bearing the divine name יהוה (YHWH), including silver skillings, marks, and gold ducats. Because of the Hebrew letters appearing on these coins, they became popularly known among collectors as "Jewish coins" or simply "Jews." Today, these issues are highly valued not only for their rarity and artistic quality but also for the unusual appearance of the divine name on official royal coinage.
