1920s German emergency money Notgeld

In the early 1920s Germany went through a period of hyper-inflation. In a very short period of time the National currency, the Mark became basically worthless. Since the economy still needed bank notes to operate local towns and companies issued their own currency. This was called Notgeld or emergency money. There are thousands of varieties of this type of money. I just added a few more types of these notes to my collection...and I wanted to share some with you.
