Pontos, Mithradates VI Eupator, Tetradrachm
79-78 BC - Pergamon - Silver - NGC - XF
Sold
Diademed head of Mithradates VI Eupator to right.
Stag grazing left on ground line; star-in-crescent above monogram in left field; ΘΙΣ (Date) above monogram in right right; BI (month) in exergue; all within Dionysiac wreath made of ivy and fruit.
Graded NGC XF Strike: 5/5 Surface: 3/5, brushed. Coin dated by the Bithyno-Pontic calendar, with BI (inverted IB?) for the twelfth month of the year, September, and the year ΘΙΣ (219th Bithyno-Pontic year), corresponding to the years 79-78 BC. The coin was therefore struck in September 78 BC. An extremely rare date, two other coins are known for this year, and only one other for this month, however inscribed ‘IB’. Possibly struck in Pergamon, the HGC only mentions the mints of Amisos, Sinope or Amaseia.

Silver
Silver can fall into your pocket but also falls between copper and gold in group 11 of the periodic table. Three metals frequently used to mint coins. There are two good reasons for using silver: it is a precious metal and oxidizes little upon contact with air. Two advantages not to be taken for granted.
Here is thus a metal that won’t vanish into thin air.
It’s chemical symbol Ag is derived from the Latin word for silver (argentum), compare Ancient Greek ἄργυρος (árgyros). Silver has a white, shiny appearance and, to add a little bit of esotericism or polytheism to the mix, is traditionally dedicated to the Moon or the goddess Artemis (Diana to the Romans).
As a precious metal, just like gold, silver is used to mint coins with an intrinsic value, meaning their value is constituted by the material of which they are made. It should be noted that small quantities of other metals are frequently added to silver to make it harder, as it is naturally very malleable (you can’t have everything) and thus wears away rapidly.
The first silver coins probably date back to the end of the 7th century BC and were struck on the Greek island of Aegina. These little beauties can be recognized by the turtle featured on the reverse.
The patina of silver ranges from gray to black.
The millesimal fineness (or alloy) of a coin indicates the exact proportion (in parts per thousand) of silver included in the composition. We thus speak, for example, of 999‰ silver or 999 parts of silver per 1 part of other metals. This measure is important for investment coins such as bullion. In France, it was expressed in carats until 1995.
