It was Lot 454 of the Triton V sale, 1/16/2002. The coin was listed as from Grynion, in Aeolis, but the inscription reads "Gyrneon" (R and Y switched). This coin was sold at CNG's eAuction 203 in 2009: It was Lot 121, and it was listed as from Gyrneion, in Aelois. The listing includes this note: Herodotus, in his History (i.149), lists “Gryneion” as one of the eleven ancient cities of Aeolis. While every reference down to the present day notes “Gryneion”, “Grynion”, or “Grynium” as the city name, all the coins are clearly marked ΓYPNHωN (“Gyrneion”). This is an example of "metatheses" or the transposition of syllables in a word. It would be interesting to find other ancient inscriptions with the city name to compare spellings. Is Gyrneion now the accepted city? Is the typo on the coin or in Herodotus?
