The flocked CCC patches Bob had in the first post are legitimate ones but not seen in wear on uniforms as they are fairly fragile. Here are some of mine. Generally they are embroidered on wool and are roughly the size of a standard US military ssi. The shield seems to be the most common shape but obviously not the only one. The repro factor is virtually zero. The cost runs from $25 through roughly $75 depending on who is bidding. They are pretty hard to find. I have walked the whole SOS looking for them and have come up with maybe one possibly two if I'm lucky.

Here is a map of the nine CCC corps areas and how to read the camp numbers.

 

 

Finally a collector can go to this CCC Camp site and figure out the what and where of most camps:
