If the ship sank in 290, it would have been during the reign of Ptolemy I. If in 280, it would have been during the reign of Ptolemy II, who supposedly commissioned the Septuagint translation of the Hebrew Scriptures.
[snip] Research on 7 recovered coins and plentiful ceramics, in particular amphora stamps, from the shipwreck led to the assessment of a date for the last voyage and ultimate wrecking around 294–290 BCE. The specificity of this date is conspicuous. A single coin (C7) is key [6]; Keen argues for a terminus post quem (TPQ) for this coin of 294 BCE ([6] at p.390). Otherwise, the ceramics and other coins (and/or choosing a potential earlier minimum TPQ dating for C7 at 310–306 BCE) collectively only define a likely possible date range for the final voyage from the late 4th century (e.g. after ca. 325/320 BCE) to the early 3rd century BC (e.g. before 280/270 BCE), quantified as likely about 310–290 BCE ([6, 7] at pp.142-145, [8] at pp.272-274).
