Hartill GCC : Page 103, # 2.45. Note that the same catalogue number is repeated on Page 104 of GCC.
Note:
Although Hartill assigned this coin to his category: Large Copper - Distinct Calligraphy. Group 4. (“Zinc Alloy”), he noted that it has a distinctly different appearance (similar to the following group which share a distinctive round 寶). Dating is suggested by the inclusion of this coin type in the Kecho Ruishu, completed around 1713.
