It was believed that if you wore this medallion around your neck it would heal your ails with “galvanic electricity”. These were also sold as Boyd’s Batteries, and there is some argument as to who actually created the battery. Boyd claims his employees stole his idea and marketed it as the Sagendorph. Neat medallion. Measures 1 3/16 inches across. See pics and email with questions. Good luck and happy bidding. Ships with USPS First Class Package.
