Daniel,The first coin is an Irish penny of King Henry III, Davi on Dublin, Class Ib. You are right in the fact that the triangle is a sign of Irish coinage in this late Medieval era. The second is a penny of Edward the Confessor gilded and made into an extravagant brooch for a person of considerable wealth.The third is a penny of William the Conqueror and the fourth is a penny of King Eadwig.Kindest Regards,Clive.
Daniel,Wow! Some superb coins you have shown. I especially like number two, it reminds me of the Venetian Grossos.I haven't seen many of these types of coins so many thanks for sharing.Kindest Regards,I'm glad you liked them. As you mentioned, the Serbian coin resembled the Ventian Grosso coins. In fact many of the early issues from Serbia, before gaining imperial status, were almost identical to either Venetian of Byzantine coins. I have a special thread titled 'Medieval Balkan Coins' in this forum. You can check this out as it has more details about each of the rulers and the coins minted. Best regards.~ DanielClive.
