You will have to call Browning to get it lettered You have a 1990 Citori. The last 3 numbers on the Citori describe the grade, among other things. Recheck the last 3 number (653) as I think it is wrong. Need serial number to date most any firearm. Check Browning's website under Support, then date your firearm. Value is determined by condition of firearm, and area of the sale.
Production figures are rarely released by Browning. Perhaps they may give you that data being a high grade gun. It is not published anywhere that is available to the public. Recommend you contact the Browning service center at link below.

In the US, the 425 grade 6 Browning was an exclusive gun that was sold by Millers Guns in Delaware. There were 100 guns made in each gauge and whitin each gauge there were silver recievers and blue recievers. I believe there were more silver ones made than blued ones(about 60/40). Current values that I have seen have them selling for around 2500.00usd.
Between 6 and 7 hundred dollars.
Need a detailed description of finish, condition, all features and markings.
