A possibly unique large-sized gold medallion of Roman Emperor Constantine I, graded Choice VF with a 5/5 Strike, 2/5 Surface by NGC Ancients, sold for $198,900 in Bonhams' September 14, 2015, auction.

The medallion had been graded and encapsulated by NGC Ancients, a division of NGC dedicated to ancient coins, in early August. It was encapsulated in an NGC Oversize Holder® because of its size—48.8 mm from top to bottom.

According to NGC's announcement in August:

"One of the most famous Roman Emperors, Constantine I is often called 'the Great' for his many achievements during his three decades in power. He is particularly well known for being the first Christian emperor as well as for founding a new capital in Constantinople.

"Some scholars believe that this medallion was struck in AD 330 to commemorate that event. It weighs an impressive 41.88 grams, which equates to a denomination of 9 solidi. Although issued as presentation pieces, these medallions were sized so that they could circulate in commerce. Only a small number would have been struck and each likely would have been personally given by Constantine I to important dignitaries."
