Money in the 17th century was calculated on the basis of pounds, shillings and pence (l.s.d., for libri, solidi, denarii, from the Latin).
2 farthings = 1 halfpenny (pronounced haypnee) 2 halfpence (pronounce haypence)= 1 penny (d) 12 pence (pennies) = 1 shilling 20 shillings = 1 pound
In addition there were other values of money used:
1 mark = 13s 4d (therefore half a mark = 6s 8d) 1 laurel = 20s (the king's head bore a laurel crown) 1 angel = 10s (the coin bore a figure of St Michael) 1 groat = 4d (therefore half a groat = 2d)
Many household accounts books of the time still typically used Roman numerals for calculations. It is therefore useful to remember the numbers used:
1= i, 2= ii, 3= iii, 4= iiii 5= v, 6= vi (v + i), 7= vii (v +i+i) and so on until 10= x, 20= xx and so on until 50= l 100= c 500= d 1000= m
Thus the number 1678 would have been represented by the letters: mdclxxviii (for 1000 + 500 + 100 + 50 + 10 + 10 + 5 + 1 + 1 + 1)
Typically the last i in a written number was represented by a j, so 4 would have been shown as iiij, or 6 as vj.
