Great coin Theodosius! I love those Thasos Tets. Nothing like a big chunk of Greek silver in your hand. I have an example. It's my largest ancient silver coin by far. Pictured next to a cent for comparison. Thasos, Island of Thrace, ca. 190 - 150 BC. Silver Tetradrachm (16.9 gm.; 33 mm.). Obv: Head of Dionysos wearing ivy-wreath right. Rev: HPAKΛEOYΣ ΣΩTHPOΣ / ΘAΣIΩN. Youthful Herakles standing three-quarters left, head left, holding draped lion's skin and club; before, M monogram. Ref: (SNG Oxford 3677; SN Delepierre 839)
That is a beautiful one, RaceBannon. The large size is definitely a very satisfying part of owning and handling one.
