1 Schilling - Marshal Lefebvre French Occupation, Trial Strike

Danzig fell to Napoleon's forces in 1807 after a brutal two-month siege, after which it was reconstituted as a nominally independent Free City under French protection — and in practice, under French military administration. Marshal François Joseph Lefebvre commanded that siege and was rewarded with the title Duke of Danzig, a title his wife Sophie is said to have embraced with considerably more enthusiasm than he did. This piece dates to the transitional period when the city's monetary arrangements were still being sorted out under occupation authority.

The trial strike status is the critical detail here. It never entered circulation.
