Switzerland
Confederation gold 100 Francs 1925-B MS65 NGC, Bern mint, KM39, HMZ-21193a. Arguably the key to the Swiss 20th century gold series, as well as very popular with world gold type coin collectors, it doesn't get much better than this in terms of quality. The only marks worthy of mention is a small dig before the forehead of Helvetia on the obverse, and a minscule one above the 2 in the date on the reverse; other than that, this is quite a stunning piece, with otherwise flawless surfaces and strong luster.
