5DM was the only German monetary unit that was issued as both a note and a coin. Your question does not say which you are asking about. It was standard circulation, so unless it is in "brilliant uncirculated" condition or has a flaw it will have little intrinsic value.
More details are needed - specifically, what denomination? "Bundesrepublik Deutschland" means "Federal Republic of Germany", so your question is similar to saying "What is a 1975 United States worth?". In any case, most German coins from that period are only worth face value or a bit more. At the time Germany switched to the euro in 2002 the mark was worth about 50 cents and the pfennig was worth about 1/2 cent, so that may help to pin down your coin's value.
