Your Half Crown is 50% silver, Dutch Guilders are partial silver, around 60% off the top of my head. The Swiss Half Francs are face value The Swiss 2 Francs is silver. Try to put them in the correct country order.
I would say that they are worth far more than 4 for a $1, paddyman. A similar silver 1960 2 1/2 Gulden sold for almost $8. https://www.ebay.com/itm/Netherland...=true&nordt=true&rt=nc&_trksid=p2047675.l2557
A Krause Catalog will give you the ASW (actual silver weight) for each coin. Then you can calculate the bullion value accordingly. It will also tell you if you have some rarer dates. You can probably check a copy out at the library.
