Payment is presumed to be made in money unless an intent to the contrary is shown.1 If something other than money is delivered by the debtor to the creditor it is possible that it may be delivered as absolute payment on the one hand or as collateral security or conditional payment on the other. If there is an agreement that it is taken as payment, it has such effect.2
