The NGC website has a modern gold example of the "Mega holder" for the largest coins/medals but has anyone seen one in hand? My only candidate is a proposed medal for the coronation of George I by Nicolaus Seeländer, a German engraver. At 131mm and 835 gms in lead, the medal is filled with symbolism and could benefit from some kind of holder but what a beast the Mega holder would be! Seelander was left in an impoverished position after his unsuccessful effort to produce this medal for the British coronation. He ended up creating forgeries of German coins of the Middle Ages, the bracteates, and used his position to authenticate his own forgeries.
