You have a nice coin, Robyn. It is a thaler from the old German State of Schwarzburg-Rudolstadt, made out of 0.536 troy ounces of silver. Friedrich Gunther ruled Schwarzburg-Rudolstadt from 1807 to 1867, a long reign for a king. His mother was the actual regent until 1814. The edge of the coin bears the inscription GOTT MIT UNS (God with us) in German.
The design of the coin changes slightly over the years, as shown in our pictures. The main picture, with front and back (upper right) is the 'normal' version bearing the reverse inscription EIN VERINSTHALER XXX EIN PFUND FEIN. A special anniversary issue (B) in 1864 has ZUR FEIER 50 JAEHRIGER REGIERUNG. Some reverses have a decorative circle around the double-headed eagle (A).
As to value, here are approximate catalog estimates:
