25 Euro Hanseatic Tartu

Tartu — known as Dorpat under the Hanseatic League and later under Baltic German administration — joined the Hansa network in the 14th century, functioning as a critical inland trading post linking Novgorod's fur and wax trade westward through Riga and Tallinn to Lübeck. Estonia's broader Hanseatic commemorative coin program has treated each city in the network as a discrete issue, making KM#115 one installment in a deliberate multi-year series rather than a standalone release.

The .9999 fineness is notably purer than the .900 gold standard common to earlier 20th-century European coinage — a specification choice driven by modern collector market expectations rather than any historical minting tradition.
