That's Bundesrepublik, and the whole phrase means "Federal Republic of Germany".
Any coin denominated in marks or pfennigs is no longer valid in Germany; those coins were taken out of circulation in 2002 when Germany adopted the euro as its currency.
It is a German Deutsche Mark.

We need more information. The words "bundesrepublik Deutschland" just mean "Federal Republic of Germany" and are not the actual value of the coin. The coin will have a number on the front, representing its value in Marks (or Pfefning).
Please post a new, separate question with the coin's denomination.

There is a website called Numista that has coin pictures. Also on eBay and so on ...
There's no such coin. Germany did not take the name Bundesrepublik Deutschland (German Federal Republic) until 1950.
Come to Germany!
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.
"Deutschland" is German for "Germany". It's not a denomination. You need to look for a value indicator, like "pfennig" or "groschen" or "mark" or "Euro" or something to figure out how much it's worth.
