Anyone ever collect some of German medalist Karl Goetz’s medals ? His books are harder to obtain than some of his medals ! Hardest one for me to get was orange book “Gotez II” took me a few years searching before I found one for sale !!! … Usually these Goetz books pop up on European auctions from time to time bring crazy prices in upward $300+ …. Just glad to have them in Numismatic Book/catalog collection

If you show each coin both obv and rev like the 1882 we can be far more helpful.   I really can't opine on the other two from this photo.   The 1882 toning appears to be natural as I can see the pull away effect around the stars and date.  This heavy tone looks to have bonded to the surface and likely cannot be removed without damaging the surface of the coin.   While I cannot say for sure, it looks like these three coins might have been stored in a leather pouch.
The 1882 coin looks to be lightly circulated and the tone is essentially at a terminal state.  As such, and knowing that none of the 1882 minted coins are significantly rare, the value of this coin is going to be $25 - $30 in today's market. 
Edited to add: @Jonson 2025 while the site does limit the size of photos it is still possible to include photos that are far better than those you supplied, here is the obv of one of my 1882 coins at 224KB.

In my opinion, the best thing about these coins is that they were handed down from your grandparents. Aside from one oak table that belonged to my father's grandmother, I have nothing from any of my ancestors other than my parents.
