Many significant events took place in 1858

• Charles Darwin published his theory of evolution by natural selection
• A gold rush began in the Fraser River area of British Columbia, Canada. Thousands of prospectors rushed to the region in search of gold, leading to the establishment of new settlements and the growth of the local economy.
• The first transatlantic telegram was sent by Queen Victoria to President James Buchanan, marking the beginning of a new era in worldwide communication

In that year, only 803,234 Sovereign were stuck by The Royal Mint in London, that’s almost 3.7 million less than were struck in the previous year, as there were 4,495,748 Sovereigns struck in London in 1857.

That makes the 1858 London Sovereign the 11^th lowest mintage circulated Sovereign ever struck in London.
