Hi all! I have this coin in my collection, and was wondering how much it was worth. It is a very rare legionary antoninianus of Carausius, LEG II reverse. This similar type, similar(ish) condition one was sold on eBay by a reputable dealer recently for about £275, but I'm not sure how mine stacks up in comparison. Their reverse looks better, but my obverse looks better (although weakly struck) https://www.ebay.co.uk/itm/Roman-br...863283?hash=item2d208126b3:g:7YoAAOSwc-df4yz9 The dark and light green deposits on my coin do not come off (and are set hard on the surface), so I don't think it's bronze disease. I'm not sure about the white deposits though Thanks!
