The story behind each coin
The Gold Mask
On 19 August 2004 the team of archaeologist Georgi Kitov discovered a massive gold mask weighing 673 g in the Svetitsa mound near Shipka. It was found in the grave of a noble Thracian of the 5th century BC – according to some scholars, King Teres (BNR). The mask is kept in the National Archaeological Museum in Sofia (Wikipedia). The coin came out only a year after the discovery.
Letnitsa
The Letnitsa Treasure was discovered by chance in 1963 in a bronze cauldron in the village of Letnitsa, Lovech region. It consists of gilded silver appliqués for horse harness from the 4th century BC, with images of Thracian horsemen and mythological scenes (Wikipedia).
The Pegasus from Vazovo
The protome (front part) of a winged horse was found by chance during ploughing in 1968 near the village of Vazovo, Isperih municipality. It is cast in gold of almost 24 carats and weighs 475 g. It is dated to the 4th century BC (Wikipedia).
Seuthes III
The bronze head of the Odrysian king Seuthes III was found by Georgi Kitov in the Golyama Kosmatka mound near Shipka – also in 2004 (Wikipedia). It is the last coin of the series and has the smallest mintage.
Why the Gold Mask costs so much
The Gold Mask is the first coin of the series and its symbol. It came out when the discovery was at its most famous. It is sought both by collectors of the series and by people interested in the Thracians. The mintage is 10,000 pieces, but the demand is greater. Its issue price was 40 leva – about €20. Today listings are around €750. See Issue price vs market price.
How to complete the series
The whole series costs about €1,450 at current medians. Start with Seuthes III, Letnitsa and the Pegasus – they are more affordable. Leave the Gold Mask for last and buy it in excellent condition, with the original certificate. See What it costs to complete a whole series.
What to watch out for
- The proof surface – look for coins without fingerprints or spots. See Milk spots on silver proof coins.
- Certificate and capsule – they increase the price. See Fake certificates and packaging.
- Toning – 999 silver darkens. Keep the coins in their capsules.
