Hello Ballf and welcome. Sounds like you have some work to do, my suggestion would be first of all to sort out the dates in order and denomination. Depending how they were stored could give a clue to grades, for imstance if they were all thrown in a jar they could be low grade and bullion value only. Up to 1920 Silver coins were made from .925 silver, and from then on up to 1947 ist was .500 silver. Just be careful how you handle and store them for now until you soft through them, there Are rare dates of both shillings and florins, 1850, 54 and 1905 Shillings Are the stand out ones and 1854, 63 and 1905 again for the florins. Most of all, have fun checking, you never know what you might find, grade of the coins are VERY important, mishandling can devalue a coin, so be careful
