Coins of India
Historians believe that coins were introduced in India sometime around the 5th and 6th centuries BC to facilitate trade.
Starting in 1848 at the first discovery of gold, it exploded into a frenzy of people abandoning families and jobs to search for treasure.
The influx of people to the area increased the population of San Francisco from a small settlement into a growing city. When it ended in 1855, many people had made fortunes and some had lost everything.
The story of the California Gold Rush begins in January 1848 when James Marshall noticed several gold nuggets glinting in the shallows of the American River. At first, the discovery felt modest enough to keep quiet, mentioned only in a small local newspaper article. Even so, news travelled quickly. Within a few months, talk of gold was spreading across towns and settlements, with people weighing up whether to leave their homes, interrupt their work and try their luck in the west. Many did just that. Some earned amounts that would have taken years to make back east, while others lost money, opportunities and, in some cases, everything they had. As the rush accelerated, businesses sprang up almost overnight, new settlements took shape and California began to change in ways no one had expected. By the time the rush eased in the 1850s, millions of dollars in gold had been extracted.

Those first few months of 1848 set events in motion. After the initial discovery at Coloma, more gold was found nearby, and Sam Brennan, a well-known shopkeeper, made headlines by racing through town with a bottle of gold dust shouting, "Gold! Gold! Gold from the American River!" Stories like this helped push the rumours far beyond California. By August, the New York Herald had carried news of the discovery to the east coast, and people were preparing journeys that would take months. The first ships reached California in February 1849, landing in a region already crowded with an estimated 40,000 miners. By 1850, ships were sailing home again with thousands of dollars in gold dust aboard, and mining techniques had become more advanced as equipment improved and larger companies entered the scene.
The rush also drew people from all over the world. Chinese migrants arrived in large numbers, as did people from Latin America and Europe, especially the French and Germans. In response to the growing international population, a foreign miners tax was introduced in 1852, aimed at reducing competition from non American prospectors. Although mining continued well beyond this period, the most intense years of the Gold Rush faded by around 1855 when many prospectors returned to their former lives.

The era also produced a remarkable photographic record. Many surviving images are daguerreotypes, early photographs made by exposing images onto metal plates. These pictures captured miners in rough work clothes, canvas camps perched on hillsides and busy makeshift towns. Photography was still a slow, careful process, so each surviving plate offers a rare glimpse into frontier life. Museums hold many of these images, and they still shape how we imagine the rush today.

James Marshall found himself unexpectedly at the centre of all this change. Born in 1810 and originally from Missouri, he worked as a carpenter and eventually travelled west to help build a sawmill for John Sutter near Coloma. When he found the gold in 1848, both he and Sutter hoped to keep the discovery quiet. Neither wanted miners arriving in the thousands or labourers abandoning the mill project. Their fears were realised almost immediately. The workforce disappeared in search of their own claims, and Marshall watched the world he knew shift around him. Despite attempting to mine himself, he never found meaningful success and later turned to running a vineyard. He never benefitted from his discovery in the way so many others did, yet he remains the figure most closely associated with the beginning of the Gold Rush.
By 1849, migration had reached its peak. People travelled from every corner of the globe. Some walked or rode across the American continent. Others sailed to Central America and crossed the Isthmus of Panama before boarding ships northward. Thousands of Chinese migrants made their way to California, joined by Europeans from countries such as France and Germany. The scale of movement in that single year was unlike anything seen before, and those who made the journey became known as the forty-niners. They are remembered today for their determination, the challenges they faced and their willingness to gamble everything on the promise of a better future.

Thousands of personal stories survive from this period. Families wrote letters back and forth across the country, often describing difficult journeys by sea or overland. Memoirs talk about hunger, illness, accidents and the harsh realities of life in the mining camps. Some achieved remarkable success. Others left with barely anything after months of effort. Some never returned home at all. These accounts offer an invaluable look at a period defined by risk, hope and the belief that a single discovery could transform a life.
