That model name does not show up in the books. Your best bet is to take the gun to a gunsmith for professional appraisal since the model and condition of the gun will significantly affect the value.
Please list all the markings on the gun, exactly as they are marked. Franchi did make a .22 semiauto rifle, but they are primarily a shotgun manufacturer. ACCIAIO? sales@countrygunsmith.net

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.
