I am also interested in this question, since I have a similar shotgun numbered 51633. I am unable to find any information.
The value of a Luigi Franchi Brescia 20 gauge shotgun in very good condition can vary based on factors such as age, specific model, and market demand. Generally, such shotguns can range from $400 to $1,200. The specific marking "91211" may indicate a production number or model distinction, which could affect the value slightly. For a precise valuation, consulting a firearms appraiser or recent sales data for similar models is recommended.
Who made a 12-gauge over-and-under shotgun stamped with A.V. Maroccui. Made in Italy and imported by F.I.E. firearms
Based on the limited info provided and the fact I can not see/handle I would estimate it to be $250 - $400 range. You may want to take it to a gunsmith to get a better evaluation of the value.
