Well clearly the last mark is EP - electro plate, that is electroplated nickle silver. Not silver. The other marks or stamps (not hallmarks - that implies a precious metal) are the maker - it is ?? & S - meaning "?? and Sons/s". The first 2 letters are in Old English / Gothic font and I can't see them clearly enough to make out. If you can make out the letters yourself, you can always Google "??&S" "EPNS" and see if anything comes up.
To be frank, I don't think it will make a lot of difference. You don't say what type of spoons they are; if they were tablespoons, or fancy dessert spoons, in a box, in very good condition, they would be worth selling. If they are teaspoons probably not. Frankly yours look to be well-used. If you like them, or they are your family spoons to keep, or use, it still really doesn't matter.
