Quarter Guinea

Quarter Guinea

The Quarter Guinea was a British gold coin first minted in 1718 during the reign of King George I. It was valued at one-fourth of a Guinea, which was a popular coin of the time. Due to its small size and limited purchasing power, it was not widely circulated and was eventually discontinued.

Great reference data. Would be nice to have more variations from different years, but overall very useful.
