Hamm's copper small change of 1635 was struck in the midst of the Thirty Years' War, when the lower Rhine-Westphalia region changed hands repeatedly between Imperial, Spanish, and Dutch-aligned forces. Municipal authorities across the region issued emergency copper coinage precisely because silver had been hoarded, melted, or requisitioned by passing armies. Hamm, a Westphalian town on the Lippe River, was no exception.

KM#45 is sparsely documented in the auction record, suggesting limited survival — unsurprising for a copper municipal issue struck under wartime conditions and intended purely for local petty transactions.
