I imagine that a lot is done by computer now, probably even the engraving of the planchets to strike the coins. On this coin they capped production at 25K, so it's not really rare, but it's a work of art. It's also on ounce of silver which in the long run is really the most value in the coin itself.
The $36 is only about five dollars over the silver price, so the cost of producing them must be pretty low.
