Silver Plated Kiddush Cups
Jewish prayer or blessing recited over a cup of wine immediately before the meal on the eve of the Sabbath or a major festival, acknowledging the sanctity of the day that is beginning. It is usually performed by the head of the household, but it may involve all family members. After the recitation, each person sips wine from the cup. In the Ashkenazi tradition, two loaves of bread on the table signify the manna gathered by the Israelites during their years of wandering in the wilderness.

Sterling Silver
Sterling silver is an alloy of silver containing 92.5% pure silver and 7.5% other metals, usually copper. The minimum millesimal fineness is 925.
Fine silver (99.9% pure) is generally too soft for producing large functional objects, and in Sterling the silver is usually alloyed with copper to give strength whilst preserving the ductility of the silver and a high precious metal content. Other metals can replace the copper, usually with the intent to improve various properties of the basic sterling alloy such as reducing casting porosity, eliminating firescale, and increasing resistance to tarnish. These replacement metals include germanium, zinc, platinum as well as a variety of other additives including silicon and boron. A number of alloys claiming firescale and/or tarnish resistance have appeared in recent years sparking heavy competition between the various manufacturers and their different formulations. No one alloy has emerged as an industry leader or standard and ongoing alloy development is a very active area.

Origin of the term
The term "Sterling Silver", in reference to the .925 grade of silver, emerged in England by the 13th century.
The terms "sterling" and "pound sterling", seem to have acquired their meaning over a while, and from several convergent sources. The first mention is that of "sterilensis" in 1078, and by the thirteenth century (the 1200s) the term sterling had appeared. "Sterling" is believed to come from the Old Norman French esterlin (meaning little star) and Old English stiere (strong, firm, immovable).

Sterling Silver - Hallmarks
A sterling silver object that is to be sold commercially is, in many countries, taken to an Assay office for testing of the purity of the metal. The item is then marked, usually via hammer and punch, with the Hallmark of that particular nation. Because this process leaves sharp edges and spurs of metal, it is generally done before the item is sent for its final wheel polishing.
The British should be singled out for its excellent hallmarking system. The stamps on British sterling silver will tell you everything you need to know about a piece. First, a stamp to indicate the purity of the silver was applied. This was usually a Lion Passant, but there were variations over the years. Next was a letter to indicate the date. The typeface, whether the letter is uppercase or lowercase, and even the shape inside which the letter is stamped, must all be taken together to determine the year. Last to be stamped was a symbol to indicate the city in which the piece was manufactured. For example, a crown of a certain style indicated the city of Sheffield, while an anchor indicated the city of Birmingham (both well-known for silver production). This system of hallmarking is still in use today.
The French hallmark for sterling silver was the head of the goddess Minerva. In fact, the French standard for sterling silver was higher than that of other nations, requiring a silver content of 950 parts per thousand. Silver items with a slightly lower grade of silver, 800 parts per thousand, were also manufactured, and these were marked with the head of Minerva, next to which was a "2". (Pieces from other nations also were manufactured in this lower grade of silver, but are stamped "800".)
In some countries, such as the United States, no national hallmark was ever adopted, although the city of Baltimore did maintain its own assay office between 1814-1830. The words "STERLING", "925", or "coin" were simply stamped into the piece. Because of this, some companies within the U.S., such as Tiffany and Gorham, adopted their own marking systems. For example, pieces from the Gorham company can be identified by a Lion Passant (or Lion Rampant, depending on the year), an anchor and the letter "G", and sometimes an accompanying number to indicate the style.
In addition to the hallmarks, silver manufacturers often applied their own specific stamp. For example, the letters "T. and Co." indicates a piece manufactured by Tiffany and Company. As mentioned above, the letter "G" indicated the Gorham Company. These stamps were as unique as today's logos, and disputes often arose when one company copied another's stamp.
The difficulty with hallmarking systems other than that of the United Kingdom was that in most cases they could not pinpoint the manufacture to a specific year, but instead to a range of years during which the company was in business. Many larger companies did put out yearly catalogs, however, and these can be used as a reference to narrow down the date of a specific piece. In fact, there are people who make a good income doing research on the history of specific sterling pieces.
Due to sterling silver having a very special characteristic in sound resonance, some brasswind instruments manufacturers also apply 92.5% sterling silver as the material for making their instruments including the flute and saxophones. For example, some leading saxophone manufactuers such as Selmer, P.Mauriat, and Yanagisawa, have created some of their saxophones made from sterling silver which they believe the instruments will become more resonant and warmer in the sound performance.
