Ep 29: How did this get there?

The BABs team took a trip down the coast to Half Moon Bay where we hiked a mile in to find a 160+ year old bank barn in a State Park that used to be a ranch. We found a lot of relics pertaining to the barn and the properties days as a ranch but I also found a foreign coin! Surprise, surprise! Me and my SP 24 coil seem to be foreign coin magnets. I'd love to know how it go there even though it's not that old.
