At first, I saw that the correct currency is not available in the drop-down of the editing page of Zutphen, City of • 6 Stuivers "Rijderschelling".
The screenshot below - taken from the editing page of another 6-stuiver piece - is what the correct information should be:
However, the editing page only allowed for these options:
When I checked the catalogue pages of other coins from the City of Zutphen, the Currency and Denomination menus were filled out correctly.
However, when I opened the editing pages, the information in the fields and the dropdown menus would flash, then changed to either ‘Unknown’ or something else upon the editing page loading.
This ‘bug’ appears to happen for every coin from City of Zutphen, but I don't know if this is a broader issue for other (Dutch) currencies. While the other 6-stuiver piece mentioned early also flashed and changed, it stayed on the correct currency and denomination.
