A copy of Jackson's Silver and Gold Marks of England, Scotland and Ireland will identify most marks.

About 100 years later, also in England, electroplating was introduced.

You never know what to expect when called out to provide a house contents valuation.

There are two types of silverplate tea sets and coffee pots.

The first are made of Sheffield silver, which describes an English plating technique developed in the 1740s, in which a sheet of sterling silver was fused to a sheet of copper, creating a strong, bi-metal sandwich that could be formed and chased like sterling silver.

To the untrained eye, it can be difficult to tell the difference between sterling silver and silver plate.

Because silver is such a soft metal, manufacturers almost never used it alone.

Most experts will be able to tell the difference between solid silver and silver plate just by handling the item. To keep its shine, silver needs to be polished regularly and frequent cleaning can wear away small areas of plating, showing the base metal below - this kind of show-through is known as bleeding. In Britain there are three standard marks indicating that a piece is made from sterling silver.

A lion passant represents English silver, a crowned harp Irish silver, and a thistle or lion rampant Scottish silver.

Some items of silver may have additional initials before the hallmark, representing the maker.

Depending on the maker's importance, these marks can often add value.

Likewise, the assay offices themselves are represented by particular marks: London by a leopard's head, Sheffield by a crown, Birmingham by an anchor and Edinburgh by a castle.
