Bad Suderode was a small spa town in the Harz region, and like hundreds of German municipalities in 1921, it issued its own emergency small change — Kleingeldscheine — to compensate for the chronic coin shortage that had persisted since the war. Louis Koch in Halberstadt was a regional printer serving dozens of these local issues, which means the technical execution here is competent but entirely unremarkable.

What distinguishes individual Suderode issues within the series is the suffix coding in the reference number — the "4/10" designation indicating a specific note within a set of ten distinct designs issued under the same authority.
