Like gold, silver is very malleable and must be mixed with other metals to make objects. Generally we use copper as other metal. Generally, the best silver contains 92.5% of pure silver. It's what is called 925 silver or 925 sterling silver. 

 

1. Take care

- Massive silver : we don't know the percentage of silver.

- Bali silver : generally less than 92,5% of silver

- Tibetan silver : silver-colored metal with very little or without silver

- German silver : alloy of copper and nickel or zinc with very little or without silver

- New silver : alloy of copper and nickel or zinc with very little or without silver

 

2. The mint marks

It's the same than for gold. All objects in silver must have a mint mark with the origin of the object : a diamond for silver, a square for plated silver.
All objects in silver of more than 30 g must have a mint mark with the percentage of silver (guarantee of the State.)

- 99.9% : amphora

- 92.5% : Minerva head or 925.

- 80% : In France only, Minerva head with 2.

- > 50% : a swan with an oblique lign

- < 50% : a swan with 2 oblique ligns

- 50% silver and 50% 18K gold (1919 to 1993) : a wild boar and an eagle
