On English silver objects, there will usually be the full set of hallmarks (quality mark e.g. lion passant for 925/1000, assay office e.g. leopard head for London, date letter, and maker/sponsor) on a main part, and each part that could in theory be separated will have just the quality mark.
So on cigar boxes, usually the base will have a full set of marks and the top lid will have just the lion passant, and on an Albert chain, the full marks will be on the crossbar, and each of the links on the chain (!) will have a lion passant.
