Perkins, Bacon and Petch, black and red engraved proofs for nine denominations, 1, 2, 3, 4, 5, 10, 20, 50 and 100 Pounds Sterling, for an unknown country, or perhaps not for a specific country at all, but the inclusion of Petch in the partnership indicates that they must have been produced between 1834 and 1852, slightly mixed grades with some having suffered edge damage of varying degrees, but an attractive set of proofs nonetheless (9 notes) £100-£150
