I guess this might be a proof set. But the 1970 5 Groschen is also listed as only being a proof coin, but the copy I have is very dull. I know it is a zinc coin, but I've seen some really shiny zinc coins in BU from Denmark, wouldn't a proof zinc coin also be shiny? The set has a little more than an ounce of silver in it, so it can't be too bad of a buy no matter what.
