Confirmation new 6d rate with locally handstruck "6d", Jamaica postal history entire headed "Duplicate. Kingston Jamaica 24th June 1854" pmk'd KINGSTON-JAMAICA JY 11 1854 dbl-arc to John Mathie, Stirling, North Britain rated manuscript "6" unpaid confirmed with handstruck "6d" which appears to be in matching ink colour. Red JY 31 1854 (applied London) and red circled M/NR (Morning, Northern Railway applied London) and STIRLING AU 1 1854 in paler black ink. Currently the only known example. The new 6d rate per half ounce was introduced MR 23 1854. Three experts on UK postal history have been approached and their combined opinion is that the handstruck "6d" is not a British handstamp, and therefore most probably applied at Jamaica (a similar handstruck "6" is known on two ingoing unpaid Barbados entires) £725
