Where to find an original series star trek badge?

I'm looking for a badge that is the closest replica to the badge Spock wears in Star Trek The Original Series. I've been looking but I can only find more modern versions of the badge worn in the recent film and Star Trek: The Next Generation. Thanks.Where to find an original series star trek badge?I've listed two Amazon links. The first is to the Science Patch. The second link is to the Science Pin.Where to find an original series star trek badge?Have you tried Ebay or Amazon? That'd be the place I'd start.
