This isn't considered to be a rare coin. sammler.com, a major German collectibles site, lists the following approximate retail values regardless of mint mark, as of 03/2011:
Moderately worn - US$1.25
Slightly worn - US$3.50
Almost no wear - US$10.40
Uncirculated - US$27.60
If its date is from the 1950s to the 1990s it's unlikely to have much extra value. These were common circulation coins until 2002 when Germany switched to the euro. They were worth about $1 at that time.
If your coin is older please post a new, separate question with the coin's date.
whats this coin worth
at todays value a US dollar is less the 2 marks on the market
Not enough information. Please post a new question with the coin's date and condition, and its mint mark if you can see it. Also, the name is Deutsche mark, just like it says on the coin.
This was a common circulation coin until 2002 when Germany switched to the euro as its currency. At that time it was worth about $1 but now is obsolete and has little or no exchange value. It may sell for roughly that same dollar in circulated condition, while a nice uncirculated one would go for about $2.
This was a fairly common circulation coin until 2002 when Germany adopted the euro. The exchange value was about US$1. Circulated ones have no additional value. An uncirculated specimen is worth about US$6 as of 02/2013.
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.
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. More information on exchanging Deutsche Marks can be found at: http://www.bundesbank.de/bargeld/bargeld_faq_banknotendm.en.php
If your question relates to the numismatic value of a 1978 Deutsche Mark coin, it is worth less than a dollar in circulated condition, and US$1 to US$2 in uncirculated or proof condition. This is the case regardless of which mintmark (D,F,G or J) you are referring to. If your question relates to the Dollar-Deutsche Mark exchange rate in 1978, US$1.00 = DM2.00 (FYI, it was US$1.00 = DM2.32 in 1977 and US$1.00 = DM1.83 in 1979).
$2 to $9000 depending upon the mint mark and the condition of the coin.
For me to relay to you the value of a coin, I will need to know the following: 1. the year in which the coin was minted 2. the mint mark and 3. the mint state.
Value All depends on grade mint mark and condition of the coin. Consult a professional coin dealer.
$1 to $7500 depending upon the mint mark, the variety and the condition of the coin.
You are asking about a 2 Mark coin from the Federal Republic of Germany ("West Germany" before Germany's reunification in 1991). There were three different 2 Mark coins issued in that years (with portraits of Adenauer, Heuss and Schumacher), and these were each produced in four different mints ("D" - Munich, "F" - Stuttgart, "G" - Karlruhe, and "J" - Hamburg). Broadly, however, the Adenauer coin is worth about US$1.50 in Extremely Fine condition and US$2.00 in Uncirculated or Proof conditions, and the Heuss and Schumacher coins are worth about US$1.25 in Extremely Fine condition and US$1.75 in Uncirculated or Proof conditions. Note that, as of January 2002, the Mark (or Deutsche Mark, abbreviated as "DM") no longer circulates in Germany, having been replaced by the Euro. They are, however, exchangable at branches of the German Central Bank (the Deutsche Bundesbank) at a rate of DM 1.95583 = €1.00 = US$1.36; thus the "face value" of a DM 2 coin is €1.022, or about US$1.39.
