The value of a Mossberg & Sons Model 385KB 20 gauge shotgun typically ranges from $200 to $400, depending on its condition, age, and any unique features it may have. Factors such as the presence of original packaging, documentation, and modifications can also impact its market value. For a precise appraisal, it’s best to consult a firearms expert or check recent sales data from reputable auction sites.
Can't tell exactly- the Mossberg 385 bolt action shotgun was made from 1964-1983. After 83, it was made as the 385 K-A, and at an unknown later time, model changed to 385 K-B. In any event, a fairly recent manufacture.
