A relatively new find only discovered in 1801, niobium plays an important role in the space industry, something acknowledged on the coin’s obverse, where a satellite maps the town of Hall from space.

Earth observation satellites are satellites specifically designed for Earth observation from orbit, similar to spy satellites but intended for non-military uses such as environmental monitoring, meteorology, map making etc.

Depicts the Guldiner silver coin of 1486, but with a difference. The design is negative and represents a coining die, a reference to Hall’s history as an important centre for minting coins. This is the first time a coin die has been reproduced on a coin, adding to the unique character of this most unusual issue.

The Guldengroschen was a large silver coin originally minted in Tirol in 1486. The Guldengroschen's name comes from the fact that it has an equivalent denomination value in silver relative to that of the goldgulden (60 kreuzer). In 1484, small numbers of "half guldengroschens" valued at 30 kreuzer were issued. This was a revolutionary leap in denomination from the smaller pieces, and surpassed even the large testones of Italy which were the highest weight coins in use. Finally in 1486 the full sized guldengroschen of 60 kreuzers was put into circulation and it was soon nicknamed "guldiner". For a long time thereafter such coins were also called "unciales" because their actual silver weight was very nearly one ounce.
