How much is a 1920s German tens of thousands or millions of Marks note worth (Reichsbanknote)?
As a general reference, according to the Sixth edition of “The Standard Catalog of World Paper Money”, the German 100,000 Mark note from 1923 is worth between 15 cents to $1. Interestingly enough, inflation was so high in Germany at this time that in 1923 there was even a 100 trillion Mark issued. Many of the German notes from this era were printed in very high quantities so most of them aren’t worth much today. I have several in my collection of varying denominations that I bought for less than $.50 each. Please check with a dealer on my links list who is up on current prices for a better answer.
