Originally, Congress provided in 1793 that all foreign coins circulating in the United States be legal tender. Indeed, foreign coins have been estimated to form 80 percent of American domestic specie circulation in 1800.

Murray Rothbard’s quote provides a historical perspective on the use of foreign coins in the United States and highlights how, in 1793, Congress made a decision to recognize all foreign coins as legal tender. The quote references a time when foreign coins were integral to the American economy, particularly in the early days of the republic. Rothbard emphasizes the fact that these coins formed a significant portion of the domestic specie circulation — an estimated 80 percent by 1800 — illustrating the reliance on foreign currency in a newly-formed nation.

The mention of legal tender underscores the idea that, for a time, foreign currency was legally accepted as a means of payment in the U.S. Despite the absence of a unified national currency, the decision to allow foreign coins as legal tender demonstrates the flexibility and pragmatism in the early American economic system. This was a reflection of the economic realities at the time, where the U.S. had not yet fully established a national currency or minting system.

Rothbard’s quote is also significant in his broader critique of central banking and the role of government in regulating money. As a staunch advocate for the Austrian school of economics, Rothbard often criticized government interference in monetary systems. By highlighting this historical moment, Rothbard draws attention to the free market forces that shaped early American finance, where currency choices were not strictly controlled by the state but rather by market demand and practicality.

This historical context is used by Rothbard to illustrate the idea that, in the absence of a robust national currency, foreign coins filled a necessary role in the American economy, serving as a real-world example of market forces determining the circulation of money. It also reflects his belief in sound money and the limits of state intervention in economic systems. The quote is rooted in Rothbard’s wider advocacy for a more decentralized and market-driven financial system.
