Thanks for the speedy reply!
Same here, the most recent reference book I have for these is Seaby's British Tokens 1970.
I have several 17th century tokens but this one is by far the best. Its currently resting in a bath of olive oil and will stay there for a couple of months after which I'll have a go at that carbon spot with a dab of acetone.
The sales records I have found are for examples in a much lower grade than this one so, hopefully, someone on here will have a recent price guide.
