Help identifying two 1715 & 1727 European coins...

I have no references or experience for this time period, so I'm looking for opinions. What is the large middle coin (1715) and the one to its left (1727)? And what are they worth? Are these silver? Thanks

5 kopeks 1889, Russia; 10 kopeks 1911, Russia; 1/2 silber groshen 1870, Prussia; 1 shilling 1727, Free City Hamburg.

 

I can not look over the details of coin 1715 year. Increase an image.

 

1715 is from Paderborn, Germany. Silver, my 1984 German catalog lists it at 50DM in Fine.

 

Whats the silver content in it, if you can give me ASW or grams that would be helpful. Anyone have more recent values? 50 DM from 1984 is impossible to convert, DM aren't used anymore, no conversion rate to Euros, plus 26 years ago... lol.
