I recently picked up this Danish Örtug that was minted on the island of Gotland (in modern day Visby). I don't have too many of these Scandinavian medievals, so I've now spent some time investigating this particular coin. Of note, this same type has been posted previously twice on CCF: http://goccf.com/t/181452http://goccf.com/t/281322
Mine is not in the best condition, but it features the Angus Dei (Lamb of God) with the body facing left and the head facing right. One of the forelimbs is tucked under the other and there is a cross atop the pole holding a banner. On the rev, there are crosses and lis. There are dozens and dozens of variations on the inscriptions: MONETA CIVITAS and WISBVCENSIS. This basic type was minted for about a hundred years (1340 to 1440 AD), but fortunately for the modern numismatist, the weight standard appears to have changed periodically thus allowing a more precise date to be determined. More specifically, from about 1340 to 1400 AD, the weight range was 1.20 to 1.37 g. From about 1400 to 1420, the weight range was 0.95 to 1.10 g. For the final twenty years, the weight range was 0.60 to 0.80 g. By the way, my coin weighs in at just under 1 g.
