A silver spoon stamped "Duparquet 5 Sterling" indicates that it is made of sterling silver, with "Duparquet" referring to the Duparquet family of silversmiths active in the 19th century, primarily known for their work in New York. The "5" may indicate a specific pattern or model number. The age of the spoon would likely be from the late 1800s to early 1900s, depending on the specific characteristics and design. To determine its exact age, further research into the specific marks and patterns would be necessary.
The "IS" stamp on a silver spoon likely stands for International Silver Co, which was a prominent American silver manufacturer. The stamp helps to identify the manufacturer of the spoon and can also sometimes indicate the silver content of the piece.

The weight of a sterling silver spoon can vary depending on its size and design. On average, a standard teaspoon made of sterling silver weighs around 20-30 grams. A larger spoon, such as a tablespoon, can weigh between 30-50 grams. To determine the exact weight of a specific sterling silver spoon, it would be best to use a scale that measures in grams.
To determine if a spoon stamped with "W R" and a cross is sterling silver, you'll need to consider a few factors.

It's best to consult a hallmark guide or a professional appraiser for a definitive identification.
