Ok here are some links to values, these are catalogue values-i.e. retail shop prices, I aim to pay half these values. That being said certain coins will make more, for rarity.
Now I feel, these coins look uncirculated(but the grading experts will know better than me on that). I'm unsure how the top right and bottom left coins will be classified, either toning or maybe environmental damage. That's a big maybe from me.

http://www.coins-of-the-uk.co.uk/values/florn.html 1900 Florin, bottom left. Old type head.
1887 Florin, bottom right. Jubilee type.
http://www.coins-of-the-uk.co.uk/values/fours.html 1887 Double Florin, top right. Arabic numeral type.
The condition of these coins is great, what I would suggest is typing the exact information of your coins into a search engine and looking at prices achieved via say
ebay. Just to get a ball park figure. However, if you don't really want the money-I'd keep them, they're great specimens. And get coin capsules to protect them. Hope this helps.
Just to add on they're all 925 sterling silver.
Shilling (.1682 Troy ounces)
Florin (.3364 Troy ounces)
Double Florins (1887-1890) (.6727 Troy ounces)
The silver purity and weight information, is just for details for you-not an indicator for price. Considering the condition of your coins, very nice coins
