The German State of Brunswick-Wolfenbuttel was still a Duchy as a member of the German Empire even though Germany lost WWW1. As such it was given the authority to authorize the production of silver and gold coins over the amount of 1 Mark. All minor coin production was issued by Germany at one of its mints. All minor business strike coinage cirtculating in Brunswick-Wolfenbuttel in 1915 were struck at the Berlin Mint (mint mark A). The only coins authorized by Brunswick-Wolfenbuttel during the leadership of Prince Earnst August, were the four silver coins commemorating the wedding of Prince Ernst and his accession; two of them being 3 Mark denominations and two being 5 Mark denominations. All coins bear the Berlin mint mark A. The three Mark denominations measured 33mm, and weighed in at 0.4823 ounce ASW. The five Mark coins measured 38mm and weighed 0.8037 ounces ASW. All four coins carried the same obverse and reverse designs, but there were two varieties of each denomination: One 3 Mark (1,700 made) carried the wordage GOTT MIT UNS on its edge while the other 3 Mark (31,634 minted) bore the words U LUNEB added to the legend. One 5 Mark (1,400 produced) has edge lettering GOT MIT UNS while the other one (8,600 struck) has the lettering U LUNEB added to the legend. Since all coins are the same except for the denominations I present only one coin for you to see. It is the 3 (Drie) Mark that has U LUNEB added to the legend.
