bill of exchange, n.All

The Bill of exchange (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the real commercial money: a written promise to pay that circulates, and — when debts cancel out — functions absolutely as money without ever turning into it.

The Bill of exchange (n.) drawn ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠for accommodation represents no real transaction at all, or one embarked on only so as to draw a bill on it.
