Holograph list of discrepancies between Mint and Exchequer weights
DXII oz
1. The whole Pile of Mint weights + 24 grains = the Exchequer Pile of sta. W.
The scale being changed, the Mint Pile – 24 grains = the Excheq. Pile of sta. weights
By a medium the whole Piles are equal in weight.
CCLVI oz
2 The outward weight of the Mint pile – 12gr = the outward excheqr weight
The scale being changed, the Mint outward weight – 12gr = outwd excheqr weight
By a medium ye outward Mint weight – {illeg} – 12gr = outwd Excheqr weight.
CXXVIII oz.
3 The outward weight but one of ye Mint Pile + 9gr = the outwa like wt of ye Excheqr.
LXIV oz.
4 The outward Mint weight but two = the like Excheqr weight
XXXII oz.
5 The outward mint weight but three = the like Excheqr weight
XVI oz.
6 The outward mint weight but four = the like Excheqr weight.
VIII.
7 The outward Mint weight but twofive = the like Excheqr weight = viij oz
IIII
8 The outward Mint weight byt six = the like Excheqr weight = iiij oz.
II
9 The two ounce Mint weight = the like Excheqr weight = ij oz
I
10 The ounce Mint weight – gr = ye like excheqr weight = j oz
11 The half ounce weight – gr = the like Excheqr weight = 10dwt
12 The five penny weigh {sic} = the like Excheqr weight.
By another tryal of the whole Pile the Mint Pile 6gr too light in one acale & the scale b{illeg}eing turned the whole mint Pile was 12gr too heavy. And by a Medium the Mint Pile is 23gr heavier then the Excheqr Pile.
