Quote: I didn't know anything gold was being coined in England back then.
As the article says, this was one of the earliest. With such apparently tiny mintages, it's assumed that gold coins at this period were mainly made as presentation pieces, rather than as a functioning part of the monetary system. Though I would note that, for this specific coin type at least, someone went to all the trouble to make a pair of special gold-coin dies, rather than simply re-use the silver penny dies that most earlier gold coins had been struck from.
Quote: And based on the photos, it just goes to show how gold can hold up in adverse circumstances (I mean the surface quality)
It's been said that if the dinosaurs had made gold coins, we'd be able to dig them up, and they'd be in just as pristine a condition. Gold simply doesn't corrode under Earth-normal environmental conditions.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
