10 Pfennig - Magdeburg-Buckau Fried. Krupp AG, Grusonwerk

Grusonwerk began as an independent ironworks founded by Hermann Gruson in 1855, renowned for hardened cast-iron armor plating used in coastal fortifications across Europe. Krupp absorbed the firm in 1893, folding it into their industrial empire while retaining the Magdeburg-Buckau site for heavy machinery and munitions work. This zinc notgeld token was almost certainly issued during the acute coin shortages of 1917–1921, when German employers routinely issued factory scrip to pay workers when Reichsbank coinage had effectively vanished from circulation.
