Didn't see that article, but browsing through past auctions I saw this solidus Valentinianus I, 364-375 from Antiochia sold for 855 euros from the Meneghini-Callas collection. Yes, Giovanni Battista Meneghini and his famous wife Maria Callas. Impressive! Picture published by Sixbid: https://www.sixbid.com/de/dr-busso-...=large&auctionSessions=&sidebarIsSticky=false
