I saw these at a pawn shop the other day (so I have no pics): an 1863 4 Ducat (holed) but otherwise in XF condition an 1875 4 Ducat (holed) but otherwise in XF condition Do they have any premium over melt value? The weights were 13.8g & tested as 24k gold. The pawn store sticker labeled them as "Australian - former earrings".
