SWEDEN. Riksdaler, 1807-OL. Gustav IV Adolf (1792-1809). NGC MS-63.KM-561; Dav-346; AAH-30. Remarkably appealing for the issue with surfaces that are blast white, semi-reflective in the fields and about as well struck as we have seen for the type. Not surprisingly, the single finest graded for the date at NGC or PCGS, making this a highly important coin for the elite type collector.
