The ref. I am looking at, Fjestad's "Blue Book of Gun Values" 2007 edition, gives a retail value of $575 for a 100% gun. At least where I live , in California's central valley, this seems a little low. It's hard for me to believe that any gunshop would ask less than $750 to $800 for a high condition Beretta o/u, esp a 20 guage..
best condition 1000.00$
Fine
50-150 USD
If it is a Superposed model 1951.
Impossible to answer since no serial number was given.
Go back to where you purchased it from.
Try gun shows, Shotgun News, Gun List, local gun shops.
value of a beretta model 413
Superposed can drop to $1000 for altered and or fair condition up to $5000 for a near new / mint gun in an original 30's case.
