US Army Corps Patches Dating

Hey all, I've got a collection of Army Corps patches but am unsure of the eras. They all appear to be cut edge 'snowbacks' save for one of the IX Corps patches & the X Corps Patch. They seem to be early merrow edges? Anyways, thanks in advance for any help/guidance!

They all look like WW2 era patches.

None have merrowed edges. All are WW 2 - KW era. Suggest u use the search button in the upper right for merrowed edge.
