Nice coins, those are .900 silver, not sure on a value as coins, since I have no idea how they grade, but I'd guess maybe 10$ a piece. They're pretty cool, I like them!
Left one is a Prussian 5 Mark and the right one is Bavaria 5 Mark. These are common date coins, there would be a bit of a collectors value on them, particularly if they are UNC, but last I knew the market on the common later German States coins wasn't very strong. They melt at about $14 each, but you should be able to get at least $20 (VF-XF), and maybe more if they look better in the hand than the pics do.
