Brass Camino Pendant

While I realize there must have been ten's of thousands of Artisan's in history throughout all the Camino's, I'm wondering if anyone knows where this Brass Camino Pendant might have (originally) come from? I found it on ebay (of course, I bought it) and it was a 'one only'. It's stamped Camino De Santiago on the back. I'm not even so sure that it was designed to be a pendant...someone could have bored the two holes into it at a later time. Has anyone seen one of these before? If so, please let me know about any background information you might have on it!

Thanks and ...Buen Camino!
PS, it's not copper looking like it is in the pix.
