KM/Coastal Eagle Question

[FW 200]

I know this is a dumb question, but could someone please tell me the difference between regular embroidered KM eagles, and Coastal defense eagles. Half the time I see them for sale, I can't tell one from the other. Again, thanks!

Navy KM would have dark blue background, while Kusten Artillery would be on feldgrau.

There are two on e-stand now, and the only difference I see in in the wreath-but it is so slight I can't tell. Both have the same background as far as I can tell.
