division into these groups has technical reasons in the production process. There has also been speculation as to the person depicted as "alpine herdsman" by Burkhard, with candidates named as Jost Schilling of Bürglen (1864–1938), Sepp Maria Planzer of Riedertal near Bürglen (1881–1964) and wrestler Franz Betschart of Ingenbohl (1871–1949). Collector's value Some of the older coins have considerable collector's value, especially the rarer batches of the 5 franc coin. The 1873 version of the 5 francs coin, produced in a small batch of 30,000 pieces, sees offers upward of CHF 2,000 in auctions. The even rarer 1912 version, produced in a batch of 11,000 pieces, upward of CHF 3,000. The extremely rare 2 francs coin of 1857, produced in a trial run of 622 pieces, is sold for upward of CHF 15,000. The rarest and most highly priced Swiss federal coins are the silver coins of 1896, minted in very small numbers. These coins are traded for amounts in excess of CHF 30,000. Gold coins The 20 francs gold coin was introduced in 1883, in the same design as the 5 francs coin at the time (with the Liberty head by Albert Walch, facing left, on the obverse, and a coat of arms designed by Albert Walch on the reverse). It contained 6.45g gold at 90% purity. Trial production of 20 francs coins were made in 1871 and 1873, in four batches: in 1871, 200 pieces of a coin with the legend "20 FR." in a wreath, and 30 pieces with a head of Liberty design by Durussel; in 1873, coins with a seated Helvetia motif by Dorer in two batches of 1000 and 80 pieces, respectively. In 1895, the Federal Council decided that the coin should be made with a novel design. From a total of 21 suggestions, a depiction of Helvetia by Neuchâtel artist Fritz Ulysse Landry (1842–1927) won second place. His Helvetia figure was criticized as too young and romantic, and the alpine panorama as too intrusive. Landry revisited his design and the revised design was chosen for the coin. It shows a female head with tresses in profile, with a garland of edelweiss and an alpine panorama . A trial run of only 12 pieces shows the head with an additional forelock which was removed as "too frivolous". The final design was still criticized as still too frivolous for a national representation, but at the
