From: https://www.biddr.com/auctions/nnlondon/browse?a=2649&l=2981656 As you all know a byzantine Solidus should have a weight of 4.5 gram or perhaps a little, little, litte bit under when struck and not clipped/filed. But not over. But this Solidus has a weight of 4.7 gram! This is first time I have encountered a coin which weight so much. I just want to ask you how often it occur that Solidus more than 4.5 gram are on auctions? Does it occur sporadically? Have a nice day.
