Interesting item. A fragment of a sheet for the production of the Kosciuszko gold coin.
A similar fragment with a single security mark is noted in the Lucow Collection.
Three edges with traces of secondary cutting, the upper edge with a tear mark. Prominent discoloration and soiling.
In passing light, horizontal lines of the watermark are visible.
Currently, opinions in the community about these sheets are divided. There is a risk that these sheets are not of the period, but are half-finished forgeries as may be evidenced by the absence of the Lake watermark in the slide.
A masterpiece item that will add variety to any collection.
