At our Auction 14 – Interesting denarius?

Do you like puzzles? The question is simple. Based on the three fragments shown below, are you able to recognize what kind of denarius it is (type and reign)? To make it easier, we will say that this is a denarius that will appear at our September auction and is a coin of extreme rarity, which was, and probably still is, a mysterious coin. We know that among you there are many experts in medieval coinage, so there should be no major problems with recognition. We will present this denarius more broadly in a few days.
