What is the value of a 12 gauge Browning shotgun serial J68824?
50-525 usd
250 USD or so
All my research indicates that the 9Z prefix to your serial number belongs to the Browning 20 gauge light weight shotgun that was made in the year 1959.If you had a 12 gauge auto-5 magnum shotgun,then the prefix would be 9V.The value of each of these will be between 350-550 dollars,depending on overall condition and a good bore.
That is an Auto-5 'Magnum Twenty' made in 1969. In excellent condition, they can reach $1400.
375-550 dollars, depending on overall condition of your shotgun.
If you mean a Browning B-2000 12 gauge shotgun then the value would be 495 dollars for a shotgun in the condition you describe.
