Stephen J‎.‎ Helliwell has produced the first book to describe Old Sheffield plate and electroplate‎,‎ along with their short‎-lived predecessors‎,‎ mercury plating‎,‎ cold gilding and close plating‎.‎ The book is divided into collectable areas‎,‎ such as candlesticks‎,‎ cutlery and alcoholic objects‎,‎ and each item illustrated is described and given an up to date valuation‎.‎ Reasons for values are discussed and explained and there is a very useful section describing the marks which are found on plate‎.‎ Advice is given on how to care for silver plate and how to be aware of fakes and reproductions‎.‎ Collectors and dealers alike will find a wealth of indispensable information in this book‎,‎ which can be kept up to date with regular price revision lists and is sure to become the standard work of reference on the subject‎.‎
