Sure, they all qualify for sterling, but some of them exceed sterling standard, which is not quite the same as calling them sterliing, and I agree that stamping them as "Fine Silver" is questionable, as is the behaviour of numerous vendors reselling them as fine silver when they do not know, and have not tested them. At least the actual silver content exceeds the stated weight.
If the makers could be questioned, they might argue that they do contain 10 ounces of fine silver, but it still does not excuse the somewhat lax wording.
