1. 1804 UK Military Bust 1/2 Guinea: These were among the last gold coins of the Guinea series to be minted for general circulation. Full guineas stopped being minted in 1799 for general circulation and was only minted in 1813 for paying the troops in the Peninsular campaign during the Napoleonic wars. This 1/2 guinea is the first year of the "Military Bust" and was minted until 1813. Due to widespread shortage of precious metal in the UK, these did not see much circulation and many were hoarded and later melted. Making these fairly scarce. 2. 1887 jubilee quintuple sovereign (5 sovereign): Quintuple sovereigns were rarely minted for general circulation. Only 3 years (1887, 1893, and 1902) were minted for circulation and all are for special occasions (1887 for Queen Victoria's golden jubilee, 1893 for her diamond jubilee, 1902 for Edward VII's coronation). This coin differs from the proof types as it does not have mirror-like fields and shows mint state luster. 1864 and 1866 Sydney Sovereigns: During the 19th century, Australia was quite literally a gold mine and was the British Empire's main source of gold bullion. So plentiful was the gold production that it became sensible to mint gold sovereigns in Australia for local demand. The Sydney sovereigns have a unique reverse and has the mint's name on it. Australia became the first colony to mint gold sovereigns and it holds an important place in its history. 1864 1866 1913 Canada 5 dollar gold coin: The history of Canada's first domestic gold coins was due to the Yukon gold rush which produced large quantities of gold as well as economic necessity for trade with the United States & the peg to the gold standard. The first gold coins were minted in 1912 and the design is still seen as some of the most beautiful ever minted. Unfortunately, in 1914 with the outbreak of WW1, most of the coins were returned and was stored in vaults until 2012 when they were released for sale.
1882 H Newfoundland $2 gold coin: Newfoundland gold coins is a interesting piece of history. As a small colony like Newfoundland it does not make much sense to produce gold coins for circulation. However, they were minted from 1865 until 1888. Most coins nowadays are damaged so finding a problem free one is hard. 1688 Mughal Empire Gold Mohur: I admittedly don't know much about these, but they are cool to own.
