Note:
HCR 58970 and 58971 are crude copies of a seal script Sheng Song Yuan Bao coin of Emperor Hui Zong (1101-1125) (cf Hartill CCC, p. 148, Figs 16.354-360). Hartill (GCC, p. 103) has provided data from the Zeno database showing that these coins are typically composed of about 50% zinc. Hartill assigns them to his category of ‘Large Copper – Distinct Calligraphy. Group 4. (“Zinc Alloy”)’. Given the use of zinc and the appearance coins of this type in the Kokon Senka Kagami of 1798, a conservative date range of c. 1550 – c. 1790 has provisionally been assigned to this coin.
