Quoted from the description of the item.

" has a plain heavy guage silver metal mount on the top. This could be Real Silver but there are no Hallmarks."

The seller is staying legal with these statements. S/he's not saying it is silver, just that it could be. By saying "silver metal" he is describing appearance, not material. While the warnings here are valid in general, in the listing, it is stating there is no guarantee of silver content.
