 The value of the metal is subject to bilateral agreement, just as is the case with pure metals or commodities which had not been monetized by any government.As an example, gold and silver coins from other non-U.S. countries are specifically exempted in U.S. law from being legal tender for the payment of debts in the United States, so that a seller who refuses to accept them cannot be sued by the payer who offers them to settle a debt.However, nothing prevents such arrangements from being made if both parties agree on a value for the coins.
