Your question needs more detail. Deutschland is not a unit/currency.
Stamps by Deutsche Post that say 200 Deutschland or 390 etc, are read as 2,00 Euro or 3,90 Euro etc. a 200 Deutschland stamp is the value of 2,00 Euro (2.00)
$24.99
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).
Deutschland is simply the German name for Germany. Without knowing the date, condition and face value, it's impossible to value it. You are talking about thousands of stamps. The value would range from completely worthless to thousands of dollars.
The absolute value of 200 is 200, and so is the absolute value of -200 .
the the http://wiki.answers.com/Q/What_is_the_value_of_a_bundesrepublik_deutschland_pfennig_in_america?

200
Unless it's uncirculated, about 30¢ (face value)
200 + 15% = 200*(1.15) = 230
% change =|original value - new value|/original value * 100% = |200 - 386|/200 * 100% = 186/200 * 100% = 0.93 * 100% = 93% (increase)
Deutschland translates as Germany
