Usually between $6 and $15 depending on condition and mint mark
It is a German Deutsche Mark.
Apart from a 10 Deutsche Mark commemorative coin with an image of an eagle on one side and the Brandenburg Gate on the other which contains about a third of a troy ounce of silver, Germany ("Bundesrepublik Deutschland" is German for the "Federal Republic of Germany") produced no silver coins in 1991.
It depends on denomination, mint mark and condition - as little as a few cents and as much as $15 or so.
Not much, the coin you're describing is a 2 Mark coin, of which millions were in circulation. Unless it is in "mint uncirculated" condition, its value is purely as a curiosity, since the Deutsche Mark was replaced by the Euro.
For starters you have to copy the wording accurately in order to search for it successfully. That should read "Bundesrepublik Deutschland", just like it says on the coin. There are a number of sites that give values, mintages, and other information. If you can read German, there's a link to one of the better sites below.

The Deutsche Mark is no longer in use, having been replaced in 2002 by the Euro. However, the Deutsche Bundesbank (the central bank of Germany) will exchange them (except for the 1948 50 Deutsche Mark bill and the 1951 2 Deutsche Mark coin, both of which were demonetized about 50 years ago) for Euros at a rate of 0.51129 Euros per Deutsche Mark. This equates to 40.90 Euros. As of March 5, 2009, this is the equivalent of 36.41 British Pounds.
