Holograph list of discrepancies between Mint and Exchequer weights
DXII oz
1. The whole Pile of Mint weights + 24 grains = the Exchequer Pile of standard Weight
The scale being changed, the Mint Pile – 24 grains = the Exchequer Pile of standard weights
By a medium the whole Piles are equal in weight.
CCLVI oz
2 The outward weight of the Mint pile – 12gr = the outward exchequer weight
The scale being changed, the Mint outward weight – 12gr = outward exchequer weight
By a medium the outward Mint weight – 12gr = outward Exchequer weight.
CXXVIII oz.
3 The outward weight but one of the Mint Pile + 9gr = the like weight of the Exchequer.
LXIV oz.
4 The outward Mint weight but two = the like Exchequer weight
XXXII oz.
5 The outward mint weight but three = the like Exchequer weight
XVI oz.
6 The outward mint weight but four = the like Exchequer weight.
VIII.
7 The outward Mint weight but five = the like Exchequer weight = viij oz
IIII
8 The outward Mint weight byt six = the like Exchequer weight = iiij oz.
II
9 The two ounce Mint weight = the like Exchequer weight = ij oz
I
10 The ounce Mint weight – gr = the like exchequer weight = j oz
11 The half ounce weight – gr = the like Exchequer weight = 10dwt
12 The five penny weight = the like Exchequer weight.
By another tryal of the whole Pile the Mint Pile 6gr too light in one cale & the scale being turned the whole mint Pile was 12gr too heavy. And by a Medium the Mint Pile is 3gr heavier then the Exchequer Pile.
