I have just listed some decent quality Silver coinage on Ebay at auction, including some scarcer dates and mintmarks. Please have a look: https://www.ebay.co.uk/sch/pbowen24/m.html?ssPageName=STRK:MEFSXS:MESOI&_trksid=p2053788.m1543.l2654 This I think is the best US: https://www.ebay.co.uk/itm/352526675838 but this one from Austria is unusual: https://www.ebay.co.uk/itm/352526683805
