Liechtenstein can look back over a long archeological tradition. Typical examples from numerous epochs are exhibited among other places in the Liechtenstein National Museum in Vaduz. Three coins are now presented as commemorative stamps.
The silver "denar" (value: CHF 0.85) discovered in Balzers and forming part of the estate of the Liechtenstein artist Egon Rheinberger, who died in 1936, dates back to Roman times (49 48 B.C.). An elephant treading on a snake is depicted on one side as well as the name Caesar.
The other side depicts priestly accoutrements such as axe, ladle, holy water sprinkler and priest's hood. In the civil war against Pompey, Caesar paid his soldiers with similar coins. The elephant signifies the fighting strength of his legions, while the priestly accoutrements symbolize Caesar's office as Pontifex Maximus.
The "florin" (value: CHF 1.00) and the "penny" (value: CHF 1.30) are part of a hoard buried in 1360 containing 26 gold and 2408 silver coins. These came to light on a building site in Vaduz in 1957. The bracteate, a silver penny from Überlingen which is struck on only one side, depicts a crowned lion with flying mane.
The coin dates from the early 14th century, as does the Fiorino d’oro, a golden florin from the Republic of Florence. The obverse side features a lily, the city symbol of Florence, while the reverse side depicts John the Baptist, the city's patron saint. This Florentine golden florin is regarded as the archetype of one of the most important late medieval gold coins.
The commemorative stamps designed by Sven Beham show in the background, indicated on maps, the places where the coins were found. The stamps were made in an elaborate process using hot foil stamping in silver and multi-step embossing. The annotation "AR" (Augmented Reality) next to the year indicates the stamp can be scanned with an app to obtain a virtual 3D view of the images depicted on the coin from all angles.
