You need to give more information. I assume it is a shotgun, but "Acier Special" just means it was made with "special steel" and we would need at least a model number to start looking for the manufacture date.
A shotgun made in Belgium
Please re-ask the question and provide the model and guage or type of gun. "Acier Special" means special steel and is stamped on many different models.

It was made in 1919. It should say "acier special" on the barrel. If not, then please describe the barrel address.

Basically impossible to value with no other information.
That marking just means "Special Steel". You need to find a model name or number to determine what it might be worth.
The term "acier special" is found on many Auto-5 shotguns. It is French for "special steel". The stamp "acier special" found on barrels are for Fabrique Nationale guns, and NOT Browning Arms Co. guns. Fabrique Nationale (FN) was the manufacturer of all Belgian Browning guns. Browning was simply an importer and bought guns with their name on them to sell in the United States. FN was licensed to make and sell some of these models World Wide outside the US. If it says "acier" on the barrel then, you probably have an FN gun. It's possible to have one of these barrels fitted on a genuine Browning gun, but then the receiver would identify the mix & match. FN Auto 5's as a custom, used the term Browning patent on many of their guns along with acier special. These guns never were sold in the US, but somehow made it to the states from overseas. Many guns were brought by returning US servicemen from WWII and so on.
