In 1880, Thomas Edison received a patent for an improvement on the electric lamp, a pivotal moment in the evolution of electric lighting that would illuminate the world like never before. This innovation, patented on January 27, 1880, embodied the principles of the incandescent lamp, marking a significant leap toward the universal domestic use of electric light. Edison's invention was not the creation of the light bulb itself but rather an enhancement that made electric lamps practical, reliable, and safe for everyday use.
With a focus on improving the filament, Edison experimented with various materials, ultimately finding that a carbonized bamboo filament could last over 1,200 hours. This discovery was instrumental in transitioning society from gaslight to the electric age, underscoring Edison's role not merely as an inventor of a bulb but as a pioneer of a comprehensive system that enabled widespread electric lighting. Beyond the bulb, Edison developed a suite of inventions that facilitated the distribution and practical use of electric light, including the development of the electric power distribution system exemplified by the creation of the Pearl Street Station in Manhattan.
This holistic approach highlighted Edison's contribution to electric lighting, showcasing his ingenuity and the significant impact of his work on modern society.
(1873-1885)
Federal officials faced a dilemma in the years after the Civil War. The Comstock Lode and other Western mines were producing large quantities of silver, but the government could use only limited amounts of it in coinage. This seems puzzling in retrospect, for silver coins were few and far between in circulation (a lingering legacy of wartime hoarding), and Americans presumably would have welcomed major infusions of silver coins. But Mint officials feared that new silver coins would be subject to hoarding as well, since the marketplace was awash with paper money, including fractional currency born of wartime need. People would have been only too happy to exchange these notes, which brought less than full face value, for precious-metal coinage.
For a time, the miners found outlets for their silver, often in coinage form, in foreign markets. Canada, Latin America and Europe all absorbed significant quantities during the 1860s. But then, for various reasons these markets became glutted. In Europe, for example, Prussian Chancellor Otto von Bismarck established a gold standard for Germany after unifying the country in 1871 and promptly dumped huge amounts of silver on the international market.
For the miners and their powerful allies in Washington these developments were doubly disturbing: Not only was it hard to sell their silver, but the market price was steadily declining. Initially, coinage did offer one escape valve: Under a long- standing law, silver could be deposited with the Mint for conversion into silver coins, for which it could then be exchanged. Having no other ready outlet, miners took advantage of this one. Invariably, they chose silver dollars, the one denomination that hadn’t been changed when silver coins were reduced in weight (and precious-metal content) in 1853. As a direct result, silver dollar mintages soared above one million in both 1871 and 1872.
But with the Coinage Act of 1873, Congress closed this loophole by suspending further production of silver dollars. And that’s where the Trade dollar came in: flexing their muscle, the mining interests won approval for this new silver coin—one that would, in theory at least, not only provide an outlet for the metal, but also open a whole new market for it in an area that was already receiving Congressional attention.
The market in question was Asia, particularly China. Some U.S. silver had found its way to that region previously, but now a full-fledged offensive was planned. The Chinese had shown a decided preference for silver coins, and up to then the bulk of American trade with China had been carried out with Spanish and Mexican dollars. The Trade dollar’s architects set out to supplant those rivals by giving the new coin a higher silver content. They even had it inscribed on the coin: “420 GRAINS, 900 FINE.”
At first glance, the Trade dollar looks much like a regular silver dollar. It’s the same diameter and about the same weight as its predecessor, the Seated Liberty dollar, and its portraiture is similar: a seated female figure representing Liberty on the obverse and a naturalistic eagle on the reverse—designs prepared by Mint Chief Engraver William Barber.
In contrast to the new Trade dollar, the regular U.S. silver dollar weighed just 412.5 grains, and the Mexican dollar weighed only 416. But the architects had miscalculated; though it weighed slightly less, the Mexican coin had a higher fineness and therefore contained slightly more pure silver. The astute Chinese recognized this and, in many provinces, gave the U.S. coin short shrift, favoring the Mexican coin.
That’s not to say the Trade dollar wasn’t used. On the contrary, over 27 million went overseas and found their way into Asian commerce, many later being sent on to India in trade for opium. Numerous pieces show chop marks—distinctive Chinese symbols—placed on them by merchants to attest to their authenticity. But usage of the coins never approached Americans’ expectations.
The Trade dollar’s biggest problems occurred not in China but at home. In a last-minute deal, Congress had made the coin a legal tender for domestic payments up to five dollars. In 1876, millions were dumped into circulation in the United States when silver prices plummeted, making them worth substantially more as money than as metal.
Congress quickly revoked their legal tender status (the only time this has been done with any U.S. coin), but the seeds of serious trouble had been sown. In the late 1870s, employers bought up huge numbers of the coins at slightly more than bullion value (80 to 83 cents apiece) and then put them in pay envelopes at face value. Merchants and banks accepted them only at bullion value or rejected them altogether, so the workers effectively lost one-sixth to one-fifth of their pay at a time when that pay often amounted to less than $10 a week.
Spurned abroad and despised by many at home, the Trade dollar soon faded into oblivion. After 1878, production was suspended except for proofs—and even those dwindled to just ten in 1884 and five in 1885.
Like many other “fantasy” coins before them, the 1884 and 1885 pieces were clandestinely struck for Mint crony William Idler and were unknown to the numismatic community until six pieces from Idler’s estate were sold by dealer John Haseltine in 1908. Notwithstanding their questionable origin, these two dates are viewed as great rarities today.
In all, fewer than 36 million Trade dollars were struck during the coin’s 13-year lifespan, including about 11,000 proofs. Production took place at Philadelphia, Carson City and San Francisco. The rarest business strike is the 1878-CC with a mintage of 97,000, many of which appear to have been melted. All high grade business strikes of the Trade dollar are rare to non-existent, leaving proofs to fill most of the demand from type collectors.
The extraordinary beauty of originally-toned proofs entices many collectors to attempt complete proof runs (excluding the virtually unavailable 1884 and 1885, of course). Indeed, any Trade dollar is highly prized in pristine condition. Points to check for wear include Liberty’s ear, left knee and breast and the eagle’s head and left wing.
