Certainty
Because almost all sterling silver is marked, you have the certainty of knowing exactly what you are buying. U.S. silver usually carries a standard mark --- the numbers "925" --- and the words "Sterling Silver," while Britain has the most thorough hallmarking system in the world, enabling the buyer to know precisely when and where an individual piece was made.
Intrinsic Value
Because silver is an internationally traded commodity, sterling silver items have an intrinsic value, unlike many antiques and collectibles whose prices are subject to fashion. To check the value of silver, type "silver spot price" into your computer's search engine, which will bring up charts of the day's trading.
Usefulness
Although not all items of sterling silver have a place in modern life, there are many that do. For instance, why not invest in a silver desk calendar, pen, mirror or picture frame? These are all items that are unlikely to become redundant any time in the near future. Having said that, some items of silver have definitely had their day, most notably elaborate silver tea services.
Style
Because silver has been made in so many styles, there are bound to be pieces to suit every taste. If you are a traditionalist, there is no shortage of Victorian silver to choose from. Should your passion be the organic lines of the Art Nouveau, then you will find find --- although costly --- examples in that style by manufacturers such as Tiffany and Co., Liberty of London and WMF. Similarly, those who love the angularity of the Art Deco period will take pleasure in the silver made by firms such as Georg Jensen from the 1920s onward.
