Bank-money is reduced to current money, by allowing for the agio, as was done in exchange with Holland; viz. say, As 100 to 120, or as 10 to 12, or as 5 to 6, so the given bank-money to the current sought. And current money is reduced to bank-money by reversing the operation. And in like manner may picoli-money be reduced to current or to bank money, and the contrary.

100 ducats banco of Venice.

In Leghorn = 73 pezzos | In Lucca = 77 crowns
In Rome = 68½ crowns | In Francfort = 139½ florins.

12 Denari make 1 foldi s. d.
20 Soldi make 1 pezzo = 4 6 Sterling.

Books and accounts are generally kept in pezzos, foldi, and denari: but some keep them in lires, foldi, and denari; and 12 such denari make 1 foldi, and 20 foldi make 1 lire.

The pezzo of exchange is equal to 5½ lires; and, consequently, exchange-money is 5½ times better than the lire money. The course of exchange runs from 47 d. to 58 d. Sterling per pezzo.
