[QUOTE="cpm9ball, post: 899967, member: 24633"]That's a good question! I do know that Morgan dollars were single-struck with a force of 150-160 tons per square inch, and proof Morgans were double-struck with higher than normal pressures. According to the VAM "Bible", the branch mints did produce a very limited number of proof Morgans to commemorate special events, so the capability of the machinery at the branch mints to double-strike medals was certainly possible. I doubt that any of the mint facilities in those days, including Philadelphia, maintained specialized equipment solely for the production of medals, but that is just a guess. It would seem that only minor modifications of the coining chamber would be necessary for the striking of medals. Below, are photos of a medal that was struck by the Mint for the 1876 Philadelphia Exhibition. In sheer volume, it is the largest U.S. medal in my collection. It is 76mm in diameter, 9mm thick and weighs a whopping 9.9 ozs. Chris[/QUOTE]
