Ten mills working 20 hours per day sufficed for coyning 90000li per week in shillings, or 15000li per day, or 150000 shillings in 10 hours & one mill for 15000 in 10 hours. And 15000 half pence is 375lwt at 20 pence per pound weight. And this is done with 5 horses & a miller at 3s per day each & 2s a labourer, that is for 20s, or 240 pence, that is for $\frac{\mathrm{16}}{\mathrm{25}}$d per pound weight, or 2d per 3lwt. And if the copper go but twice through the mill, it will be done for $\frac{\mathrm{4}}{\mathrm{9}}$d per pound weight.

One cutter dispatches 26 pieces in a minute that is 780 pence in an hour that is 40lwt in an hour or 320lwt in 8 hours. And this is done with a moneyer & a labourer to bend the scissel &c for 7s that is for $\frac{\mathrm{1}}{\mathrm{4}}$d per pound weight.

One flatter with two men dispatches 1$\frac{\mathrm{1}}{\mathrm{2}}$lwt in a minute, 90lwt in an hour & 720lwt in 8 hours for 4s, or 1lwt for $\frac{\mathrm{1}}{\mathrm{15}}$d.
