Many of us don't apply our own makers mark, which is unique at your chosen assay office, but have them apply it when hallmarking an item. If small it would probably not work well in soft clay, so that raises the question of how big to have it.
A good size for stamping hard metal, together with the hallmark, would be between 1.5 and 2.0mm high, depending on your eyesight. Once registered, the assay office can also use a laser mark, which is more suitable if an item is fragile, or difficult to stamp. Dennis
