Last month I opened a box full of medals I had accumulated in the 1960-75 timeframe. Included was a partial set (28) of the Longines Symphonette Great American Triumphs medals. They were purchased by my Uncle Elmer Reed on a monthly subscription basis in 1971 and 1972. They came in two-medal boxes

Data included the following:

• Mintage: 5,000 (my set is marked P 696 on edge).
• Composition: produced in both 99.99% silver, and 92.5% sterling silver. (mine are edge marked sterling)
• Size 39mm - slightly larger than a silver dollar.
• Weight: 34 grams (1.109 ASW)

I don't know if this helps. I discarded the paperwork which came with the medals keeping only these notes and one of the boxes. I transferred the medals to one of my many coin cabinets. I never thought much of these types of issues. However, these are attractive, and well executed medals.
