In the North, the sale of government bonds was the one measure for raising funds that seemed to work. Even that, however, with the lure of compounded interest to be paid in gold at a future date, failed to raise more than about half the needed amount. So the Union faced a real dilemma. The only options remaining were (1) terminate the war or (2) print fiat money. For Lincoln and the Republicans who controlled Congress, the choice was never seriously in doubt.
