Virtually all the York coins were struck in the period 28th January 1642/3 to 28th January 1643/4. The type 3 halfcrowns were later than the type 2s based on the wear to the horse punch which was the same for both types. The Briot style shilling dies were later still according to the wear seen on the punches. We know that the Pocklington Hoard contained a few dozen type 3s which were fresh as from the mint when found. The most likely reason for their concealment would have been the breaking of the Hull siege by Parliamentary troops on the 11th October 1643 and their subsequent advance to around Stamford Bridge, thus threatening York, at which point the Royalists retired to the city for the winter and left on the 28th January 1643/4 to head north and confront the Scots Covenenters who were advancing on Newcastle. Whilst it doesn't confirm these months as the time they were struck, it is likely that more silver would have been available during the summer when they were enjoying success on the battlefield than the following winter when contemporary diaries record that there was little coining taking place due to lack of silver. Once the Northern Army left in the January, troop numbers in York dropped from about 10,000 to 8 or 900 which also demanded less coin. The cavalry left for the north while the remaining troops were foot soldiers, suggesting the shilling was a more practical denomination at this point in time. A cavalryman earned 2/6d per day, the foot soldier a shilling - when the got paid which wasn't often.
