Hello Claudio
Welcome to the Forum.
The exact same pattern of General Service button with a King's crown was in use between 1901 and 1953. It is not always easy to say which button is World War 1 and which is World War 2.
Sometimes the maker's name on the back will help decide whether WW1 or WW2 period.
The colour of the metal button gilt/silver (brass/white metal) is the difference between regular soldiers (gilt for officers, brass for other ranks) and volunteer soldiers (silver for officers, white metal for other ranks).
Plastic buttons (found in one of several different colours) are most likely to be World War 2 period.
For a simple 'General Service' pattern button it can be quite complicated. There are a few members on this Forum who collect all the different types of General Service button. They may be able to help further.
