Austrian 500 Schilling 1980 Silver Wedding

I'm not entirely sure about a 1980 Austrian 500 Schilling coin specifically commemorating a "Silver Wedding," as my notes from decades of handling Austrian issues don't list one for that event. Austria did mint 500 Schilling silver coins in 1980, likely as part of their standard commemorative series, which often highlighted cultural or historical milestones; for instance, some from that era featured motifs like the Wiener Philharmoniker or state anniversaries, struck in .900 fine silver with a diameter of about 37 millimeters. These pieces were produced by the Vienna Mint, a institution I've visited more times than I care to count, and they typically weighed around 20 grams, appealing to collectors for their heft and detail. What I do know is that exact mintages for many 1980 coins remain unclear, possibly due to incomplete records from the period, though estimates I've heard suggest figures in the low hundreds of thousands for popular designs. If this "Silver Wedding" variant exists, it might be a lesser-known issue tied to a royal family's milestone, but I'd advise verifying through reliable catalogs before bidding on one—I've seen fakes that fooled even sharp-eyed enthusiasts. That said, the broader 1980 series holds its own quiet charm for those who appreciate solid, unadorned silver work.
