Why is this patch so unique? (Edit: I added the photo as a comment) I was given this patch. All others I found are simple embroidery. This is ‘3D’. It has 4 pins on the reverse side. Can anyone identify what this patch is and/or its age?

This patch appears to be a 3D raised-style patch, known as a "loomed" patch. It appears to be an older style of patch, as loomed patches became increasingly popular in the mid-to-late 1960s. The pins appear to be used to attach the patch onto the material of the garment or article it was meant to decorate. The unique shape and style of the patch and the pins make it difficult to identify exactly what kind of patch it is.
