Gold bullion is based on the going market for the metal and is usually purchased in bars with a troy ounce weight of about 400. The 1893 Deutsches Reich 20-mark coin weighs only about 8 grams, so it would not have the same value as a bullion brick, but a coin in good shape can be worth over $200.
A 10 pfennig is a coin, not a note. The value of a 1917 10 pfennig coin depends on its condition. The typical value is between 20 c and 8 US dollars.
A 1889 Deutsches Reich 20 Mark gold coin is 90% pure (10% copper). It should weigh 7,9649 g, giving it a gold content of 7,1685 g.

You are asking about a One Mark coin from the German Empire (KM#7). It is about the size of a US quarter, weighs 5.5 grams, and is 90% silver, giving it an ASW (Actual Silver Weight) of 0.1606 troy ounces. 6,155,000 such coins were produced at the Stuttgart mint (mintmark "F") in 1874, making amonst the most common of the "Deutsches Reich" (German for "German Empire") 1 Mark coins. With silver at a value of US$39.65 per troy ounce (as of April 7, 2011), the coin's "melt value" is US$6.37, higher than the numismatic value of the coin in "worn" condition. According to the Standard Catalog of World Coins, an example would be worth US$2.50 in Fine condition, US$8.00 in Very Fine condition, US$40.00 in Extremely Fine condition, and US$125.00 in Uncirculated condition.
