About 25 Euro Cent
Unless it's uncirculated, about 30¢ (face value)
1¢. At the time it was replaced by the euro (2002) the Deutschmark was worth about 50¢ U.S.
It is worth nothing. The Germans no long use the mark, but are on the Euro. When it was used a 50 pfennig was about 5 cents. One pfennig was a penny.
This coin is no longer in circulation, having been replaced by euro-cent coins in 2002. At the exchange rate in effect at the time, it was worth about a nickel.
This coin was part of the old Deutschmark and pfennig system that was used prior to the introduction of the euro in 2002. At the time the exchange rate was roughly 1 DM = 50¢ U.S. There were 100 pfennige* to the mark, so your coin is, I'm sorry to say, only worth one-half of a U.S. cent. (*) "Pfennige" is the plural of "pfennig". The word is the source of our "penny".
Please post a new, separate question with the coin's denomination.
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.
"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.
This was an extremely common circulation coin until 2002 when Germany switched to euros. At that time it was worth about 5¢ in US currency. It has no added value as a collectible except in uncirculated condition, in which case it might sell for all of 35 cents.
Unless it's uncirculated, this coin (10 pfennige, rather than a pfennig with a 10) is only worth face value, about 5 cents. It was a common circulation coin until the euro was adopted in 2002.
This was a common circulation coin until Germany adopted the euro in 2002. In average condition it's only worth only its face value at that time, one US cent. In almost-uncirculated condition it might retail for about 35¢, while an uncirculated one would sell for about 75¢.
