Countermarked

To countermark means to add a secondary mark, usually a stamp, incision, or other identifying feature, to an existing object. This is most frequently done on currency, but can apply to various goods, documents, or even persons. The addition serves several purposes, including authenticating the item, indicating a specific condition or provenance, validating it for a specific region, or denoting a change in value or status. Countermarking often involves meticulous records, linking the added mark to a particular authority, date, or purpose, thereby creating a unique identifier for tracking or verification.
