10 Cash - Dazhong Tongbao, with Shi

The Great Zhong State was the short-lived regime of Chen Youliang, a former fisherman's son who rose through the Red Turban rebellion to challenge Zhu Yuanzhang for control of China during the Ming foundation wars. Chen proclaimed his dynasty in 1360 and was killed at the Battle of Lake Poyang in 1363 — one of the largest naval engagements in history — leaving his son to hold out until 1364. Coins continued to be cast under the Dazhong era name through the transitional period as Zhu consolidated power, which accounts for the extended date range assigned to this type.

The "Shi" denomination marker places this among the heaviest and largest issues of the series, cast when bronze supplies and political urgency both ran high.
