A selection of five hallmarked silver napkin

They are all quite tarnished  and discoloured, some more than others, and most are pitted. There is a plain napkin ring which the hallmark has virtually rubbed off completely. The napkin ring which has a stepped rim and is engraved MCL, is badly pitted and has lots of small dents and scratches, engraving still quite detailed. The hallmark on this is badly rubbed and only partly legible. There is a plain napkin ring with a rim which has a long, deep scratch near the edge. There's a textured napkin ring which is badly discoloured and tarnished on the inside.
