James Murdock Jr., Die Sinker of Cincinnati
Anyone follow James Murdock Jr.? He was a die sinker in Cincinnati. I just ran across him as he was the issuer of a Columbian Exposition store card I had picked up.
David Schenkman had a good article on him in the May 2018 issue of The Numismatist. Here's a photo of James Murdock Jr. from the article:
His company, Murdock Stamp and Speciality Company, was acquired by Wiley W. Osborne's company, later known as Osborne Coinage Company, which claims to be America's oldest private mint via it's acquisition of Z. Bisbee Co.: https://www.osbornecoin.com/.
