2½ Dollars – United States

In 1829, the United States operated under a bimetallic standard, where both gold and silver were legal tender and could be minted into coins at a fixed ratio set by the Coinage Act of 1792. This system established a 15:1 ratio, meaning one ounce of gold was valued at fifteen ounces of silver. However, the official mint ratio often diverged from the global market value of the metals, leading to chronic instability. When the market valued one metal more highly than the mint's fixed price, that metal would be exported or hoarded, while the other flooded into circulation—a principle known as Gresham's Law. By 1829, silver was undervalued at the U.S. Mint compared to Europe, causing much of the nation's silver coinage to disappear from everyday use.

The practical currency in circulation was a chaotic patchwork. While federal coins were the official money, they were scarce. Instead, Americans primarily relied on a vast array of paper banknotes issued by hundreds of state-chartered private banks. These notes were promises to pay in specie (gold or silver), but their actual value fluctuated wildly based on the perceived solvency of the issuing bank. Notes from distant or dubious banks often traded at a steep discount, creating confusion and risk in commerce. Furthermore, the Second Bank of the United States (BUS), chartered in 1816, held a unique position as the federal government's fiscal agent and was meant to regulate this chaotic system by demanding state banks redeem their notes for specie, theoretically restraining excessive paper money issuance.

This financial landscape existed at the center of a fierce political battle. President Andrew Jackson, inaugurated in March 1829, deeply distrusted paper money and banking elites, viewing the BUS as an unconstitutional and corrupt monopoly that favored the wealthy over ordinary citizens. His hostility set the stage for the "Bank War" of the 1830s. Thus, in 1829, the currency situation was not merely an economic issue but a deeply political one, defined by the tension between a scarce and unstable metallic base, a proliferating and unreliable paper system, and a growing populist movement demanding a more democratic financial order.
