Could anyone recommend grading guides, preferably online, for the following types of silver world coins? I generally collect lower-mid grade examples . I have just been looking at slabbed examples, but I'd like something more comprehensive. Thank you
German States 5 Marks
Peru Sol (.9 and .5 silver)
Spain 5 pesetas
Italy 5 Lire
France 5 Francs
Britain Crown and 1/2 crown
Plus any other miscellaneous "crown"-sized coins
