The medal's obverse bears eight segments depicting scenes from different olympic winter sport events, surrounding center field with Lake Placid Olympics symbol and XIII OLYMPIC / WINTER / GAMES / LAKE / PLACID / 1980; signed at right, © (JOV monogram)
The reverse bears calendar panel flanked by two olympic torches. Pine cones and 1980 at top.
The circular medal measures approximately 76.1mm in diameter and was struck in various materials. No mintages are reported and I am speculating on the existence of a silver variant. The fourth variant bears both MACO and SPORRONG on the edge and weighs significantly more than the very similar third variant. Was is produced to spec for the Scandinavian Sporrong Mint or maybe in license by the Sporrong Mint? Any additional information would be appreciated.
