At its second-ever auction appearance in September this year, this 1854 Deep Cameo gold dollar sold for $720,000. Halfway through 1854, the Philadelphia Mint started producing Type 2 gold dollars. These were thinner and had a larger diameter than Type 1 coins, which many people complained were too difficult to locate in a pocket or purse. As a result, this example is one of the last Type 1 coins ever produced.

The dollar was previously sold at auction in 1985 when it was bought by collector Harry Bass for $68,750 – the equivalent of around $189,640 today.

US coins and bills worth far more than their face value
