Which nation did the first proof coins (and when)?

Hello Group
Which country minted the first real proof coins? I know Stateside the first ones came around 1817, so Im guessing whoever did that was aprenticed over in England, but were they the first?
Thanks

edit - ok, yeah, I was thinking of this. Like he says, some earlier types might resemble proof quality, and the later types of Charles II more fully fit the definition. But Breen says the 1651 half is it.
