@Jo in https://philamuseum.org/collection/object/90644 which uses that phrasing the geography metadata further down the page specifies “Probably made in Netherlands, Europe”
@Satsuma There were a few auctions I found online associated with the same assay master that id'd their contents as "Jamaican Silver" which threw me into doubt.
@Jo huh interesting! possibly he was also the assay master for certain internal trading / verification then?
@Jo ha yeah i thought there was a chance that we’d found the same listing! glad i could provide such a definitive answer then :)
@Satsuma Oh word missed that line! That is exactly what i was looking at too.
