Yes. Many pieces of antique silver are not marked. The first early silver pieces had guild markings to show the maker was a gold or silver smith, the first "hall marks". But the amount of silver in the pieces might vary a great deal. Some countries such as Great Britain instituted requirements that silver be inspected and meet a specific standard. They were then "hallmarked" that they met the government set standard. However the amount of silver that represented standard varied from country to country. Sterling or 925 parts pure silver out of 1000 we tend to think of as the silver standard today. However there were times and places where the standard was as low as 700/1000 and up to 950/1000. Unmarked pieces can be tested by a Jeweler to determine the amount of silver in a piece.
