Counterfeiting Clause

Original public meaning

The clause was a late addition, folded into a broader Law of Nations power rather than debated on its own. On 17 August 1787, Madison's notes record Gouverneur Morris arguing the Convention needed to "extend the authority farther, so as to provide for the punishment of counterfeiting in general," since bills of exchange "might be forged in one State and carried into another," and another member raised the related risk of citizens counterfeiting foreign paper. Oliver Ellsworth then folded all three concerns into one motion — "to define and punish piracies and felonies committed on the high seas, counterfeiting the securities and current coin of the U. States, and offences agst. the law of Nations" — which passed nem. con. (Records of the Federal Convention, Farrand ed., 2:315.) Madison's Federalist No. 42 confirms the clause's narrow, derivative purpose in a single line: punishing counterfeit securities and coin "is submitted of course to that authority, which is to secure the value of both," i.e., it follows directly from the Coinage Clause power rather than standing as an independent grant.

St. George Tucker's 1803 annotations to Blackstone read the power as "a natural incident" to the borrowing and coinage powers, but flag that Congress had already stretched it: the act "to punish frauds committed on the bank of the United States" (5 Cong. c. 78) penalized forging bank notes, even though the constitutionality of the Bank itself — and by extension Congress's power to protect its paper under this clause — had been "warmly contested." Tucker adds that "it has been confidently said" Washington could have found a rejected Convention proposal to authorize a national bank in the (then-secret) Convention journals he himself kept as its president, had he looked. Tucker treats the episode as a caution about clause creep: "the most unauthorised acts of government may be drawn into precedents to justify other unwarrantable usurpations."

gap

No source in this batch supplies a direct founding-era statement on whether the power reaches non-counterfeiting uses of forged currency (the modern narrow-reading question). Tucker's Bank-note objection is adjacent — a dispute over how far the coinage-adjacent power can stretch — but does not address the counterfeiting text's own outer edge.
