I figured his design for the coin came with far more restrictions having to meet standards not present with notgeld, there was far more license taken thus the more interesting coinage designs. All the same it doesnt strike me as one of his better works even for what it is.
Certainly it is the interesting nature of notgeld that the themes are so wide and varied, each so different. Cheap as dirt some, and often times poorly minted. But there are some real outstanding ones as well to be sure, lovely works of art, two I have always been a fan of and the coin set that attracted me to notgeld would be these Duren issues:


^^ I wouldnt have been shocked if someone said this soldier was Goetz as well or by the same person who did the aachen coin, they seem similar...I have no idea who designed most of the notgeld I own.
I do love the simplicity of the notgeld like the first example in this thread, not that they were all simple but more, like you say, reality of the times, expediency and there are some impressive designs all the same.
I am sure there are many Goetz designs I haven't seen but as a fan of your site and collection, I have spent quite a bit of time rummaging through your website showing it to others. I think I have seen a good sampling of the fine examples of his medals. I love his unique style and like I said before, those designs are outstanding with what seems to be, on many, what may have been more freedom with the designs and the great high relief. True works of art.
I love everything about this frau coin, I love that they used the subject, the antithesis of the beauties on most other coins. I dont know if a statement was trying to be made, but the idea in and of itself was great. Some times simple is better in my opinion. You could easily say that the Aachen notgeld is a classic example of real skillful use of the 'do more with less'...the large fields of the bonnet with scant detail, contrasted with the simple lines that make up the face but depicts so vividly the subject. Also I like the more simple (whether refined or raw) coins in general.
I have several of those notgeld you have posted...I was unaware they were by Goetz. The style of those coins, I assume because of lower relief, didn't remind me of his work but I can see it. I am thrilled I own several Goetz designs

You just made my night!
