More history than you probably want to know:
The Nazi Party won the election in January 1933. A large amount of their financial backing came from industrialists that were trying to break the hold that increasing union membership held in the country. One of the Nazi Party's goals was Arbeitsfriede (shown on the front of the token)--meaning Labor Peace, or basically freedom from unions. Which they pretty well destroyed that year.
I'm wondering if this was some kind of token, meant to commemorate when the Nazi Party "fixed" the problems in the country that were being caused by the unions and various undesirable people. The "regular" people saw that things were getting better, and it was some time (possibly years) before they heard about the labor camps that were built that year.
Still researching, but definitely a token, and not Notgeld. Notgeld always listed the amount the coin was worth.
Edit: I noticed that the person had written on the 2x2 "donation medal." I thought it might refer to the Winterhilfswerk charity campaign, but all the tokens I saw that were given out for large donations all named the charity on the coin. Although the token does say "give us this day our daily bread" on the back, implying it's part of the charity, which gave food and coal for heat to the poor each winter in Germany.
