Hamburg 1798-OHK schilling
"Hamburg, Stadt, Schilling 1798. Goldabschlag zu einem Dukaten. NGC MS63. (Germany, city of Hamburg, schilling of 1798, off metal strike in gold.)"The SCWC lists this type in billon for 1778 and 1790-95. Regular ducats exist for 1798 so we don't know why this off-metal strike was felt necessary altho plenty of other examples exist in the numismatics of north Germany and the Netherlands.
