A hallmark struck twice
One piece carries two marks side by side — and the second is not a forgery.
The first mark is almost entirely worn, the second is crisp and sits a few millimetres to the right. This was done at re-assay: if a piece was melted down or altered, the mark was struck again.
Koval shows the spot under a magnifier and gives both dates on the label. He says visitors ask about the second mark more often than about the object itself.
