Coin Typology of


Minting System and Typology

The meaning of the legend TPIH or TPIE on small silver coins (with a diameter of around 8–10 mm and a weight of ca. 0.45 g) has long been debated in numismatic research.1 While some scholars advocate for assigning it to a city of Trieros, others believe it represents a nominal name, such as a trihemiobol.2 These coins are dated stylistically to the second half of the 5th century BC.3

First, two groups can be distinguished iconographically. One depicts the laureate head of Apollo to the left or right on the obverse and an upright laurel branch with one of the two aforementioned legends in quadratum incusum on the reverse.4 A second group bears the same legend on the reverse in quadratum incusum without any figurative addition and a horse protome to the right on the obverse.5 Despite similarities in diameter and weight, as well as in find spot,6 the affiliation of these two groups can certainly be doubted. Other textless coins with a horse protome on the obverse and a quadratum incusum on the reverse are also assigned to this series.7

Regarding the attribution of these coins to a city, Tr(i)eros, or a tribe of Trier, the research is based on reports of Strabo, Stephanus of Byzantium and Theopompus,8 who locate the Thracian Trier tribe between Maroneia and Abdera on Lake Bistonis.9 Based on the fact that some of the small coins were found near Olynth and in the city itself, as well as on stylistic similarities of the head of Apollo featured on the small coins to that on those of the Chalcidian League, the excavators D.M. Robinson and P.A.Clement concluded that the coins were minted in Olynth.10Based on stylistic comparisons, they dated the coins to ca. 430–400 BC. However, due to their weight, the trihemiobols cannot fit into the Chalcidian series because they are too light.11 These coins with the laureate Apollo were also attributed to the Clacididan League by S. Psoma. Concerning the coins with the horse protome, S. Psoma advocated that these emissions should be regarded as coins with a registered denomination and assigns them to Alexander I and Perdiccas II on the basis of a single piece of a similar type with an entire horse on the obverse and the letters ΔΙΟΒ in the quadratum incusum of the reverse.12 The nominal designation on the coins had become necessary after the reduction of the monetary standard.13

The inclusion of the TPIE/H marked coins in the type list of Thracian coins is due to the convention that many of these coins are still assigned to the Thracian area in collections and literature.
