I wouldn't worry too much. You'd expect a few 'buggers' here and there in a book like that. A collector would be mad to spend a fortune on a coin based on information from a single source. It's a good book, I like it. Seems easier to navigate than Spink, the prices on the couple of coins I've looked at so far seem more realistic, and I had a third point but I've forgotten (oh hang on I remember - had a farthing variety that Spink didn't list). cheers Garrett.
