Seleukis and Pieria, Dated year 18 (92/91 BC). Obverse: Tyche with Turreted crown facing right & surrounded by border of elongated beads. Reverse: Thunderbolt of Zeus on a fancy stool & inscriptions, all within a wreath. AR Tetradrachm: 15.00 gm, 34 mm, 12 h. Very rare date. BMC-; DCA 697. I didn't want to present this coin until it was photographed again. The printed catalog & online catalog shows the coin slightly out of focus & darker than the coin actually is. The descriptions of the coin also have a typo, stating the diameter at 24 mm, it's actually 34 mm. I fell in love with the high relief portrait of Tyche, & the immense flan gives the coin a medallic appearance. When I saw the low estimate of 500 British pounds I was determined to bid on the coin . The bidding began at a frenzied pace & soon reached the final bid of 3 times the estimate ! I felt like a kid in a candy store who lost control . The coin was mine at 3 time the estimate . I felt foolish for paying so much, but when the coin arrived the guilt disappeared. The coin in-hand is mesmerizing . I don't know anyone who collects this coin type by date. Do any CT members know just how rare the date of this coin is ?
