I went to a local coin show recently and found these items in a dealer's coin box, marked for $18 each. I am not a big fan of the Olympics, but the coins looked nice so I bought them. Both are from Austria, and commemorate the 1976 Winter Olympics held in Innsbruck. The Krause catalog states that the coins are 36mm, silver 0.640, ASW: 0.4924oz, and should weigh 23.9300gm. One of mine has a weight that is close but the other weighs significantly more. Is it a catalog error or something else? Austria 100 Schillings 1976 Winter Olympics Innsbruck - Emblem (KM-2926) Weight: 23.87gm (close) Austria 100 Schillings 1976 Winter Olympics Innsbruck - Building (KM-2927) Weight: 24.21gm (not so close) The eagle on the reverse looks almost like an Aztec deity. Innsbruck also hosted the 1964 Winter Olympics: Austria 50 Schillings 1964 Winter Olympics Innsbruck (KM-2896)
As for the weight, my catalog (Schön) says the weight is 24 g in both cases. The "building" is a combination of several buildings in Innsbruck, such as the Helblinghaus on the right and the Stadtturm (City Tower). That "square eagle" was used on several Austrian 100 Schilling commems between 1975 and 1978. Interesting design, but none of the reverses harmonized with that obverse ... By the way, the small Tyrolean eagle at the bottom is a mintmark; for the 1976 Olympics the old mint in Hall near Innsbruck (today an interesting museum) was temporarily reactivated. The Vienna mint had the city's CoA as a mintmark on these coins. Christian
