What is the value of a German Nazi flag from World War 2 original made of cloth?

Simple answer, it depends how large the flag is and how rare. If it is a plain red flag with a double-sided white circle with a swastika, it is very typical. Some of the smaller versions are actually more valuable because of demand. If it is about 3' x 5' it is worth about $100-150. A very large flag or banner up to 20' feet long, it could be worth $500 or more. These prices are for very good condition flags. Simple answer, it depends how large the flag is and how rare.
