The time qualifier correctly specifies 1662 with no end date (valid_to: null), matching the passage's temporal scope. The context accurately reflects the location restriction ('at the Turk's Head coffee house in Exchange Alley'). The quote appears verbatim in the passage and directly supports the claim about the price of right coffee powder.
