Dendrochronology reveal that most of the timbers used to build the ship originate from the Basque Country of northern Spain dating from c.1449. The discovery in the spring of 2006 of a French "petit blanc" (small white) silver coin inserted into a cut out in the stempost/keel join was a major step forward. Placed, perhaps, as a token of good fortune at the start of the ship's construction, this coin was minted in Crémieu in the Dauphinois region of France between May and July 1447. Tree trunks found under the hull and forming the support for the ship when under repair, have a dendrochronology date of 1468 – 1469.
