Andrea Contarini was doge of Venice from 1367 to 1382. He served as doge during the War of Chioggia, which was fought between the Venetian Republic and the Republic of Genoa.
Contarini was noted for his personal bravery during the war. He also led a fundraising effort in which he personally liquidated his fortune for the country. Though in his seventies, he took personal command of the Venetian Navy (with Admiral Vettor Pisani as his chief of staff) and led troops in the critical Battle of Chioggia.
NGC has graded 15 in higher grades of this Doge (MS63-66), and this is the only one in MS-62
PCGS has graded none of this Doge's zecchinos
I can see that this same coin was formerly for sale by APMEX and also on the Wal-Mart website!

So, you could have had a 650-year-old gold ducat of Venice delivered to your house along with toilet paper, cereal, and tooth paste. As preeminent merchants, maybe the Doge would be proud.
