Ta Blair, that makes a little more sense.
"effects of trade" was an instrument used during the renaissance
but I am unable to find out, or understand much about it


"Blair"
In translating, you cannot depend on word by word translation
to convey the proper meaning.

An "effet de commerce" translates as "a negotiable instrument".
A negotiable instrument evidences to the holder a debt of money
and is used as his payment (i.e. a bill of exchange)

The Geneva 1865 revenue showed payment of the 5 centimes
tax on a bill of exchange valued between 1 and 100 francs.
