I actually got mine for coin pics (I also Metal Detect), but I could not take a decent close-up to save my life, until someone posted this:

Amazon.com: Celestron 44302 Deluxe Handheld Digital Microscope 2MP: Camera & Photo

$40 and free shipping.

Sorry I didn't have any Jig pics to post (lol, not that I'd want anyone getting that good of a look at them), but this will at least give an idea of the quality of pics it takes (hands free) in the event anyone might be interested.
