France's government has banned sending currency by mail — including coins, cash and all forms of precious metals.
BullionStreet notes that the legislation, which was approved May 23, was not announced by the government at the time and has been little reported on by media outlets.
Published via Legifrance, the law states:
“the insertion of banknotes, coins and precious metals is prohibited in mailings, including the insured items, registered items and items subject to formalities certifying deposition and distribution.”
The law came into effect June 1.
