Have it inspected by a good gunsmith
Which model?
Model variation
I have a marlin model 60 with a gold trigger..the price difference is not by much if any at all..they both cost the same. some gun shops will charge more, but most usually don't and charge the same. A model 60 with etching and wood work can sell for more than one with just a gold trigger.
Might have been replaced.
About $350.00
Can not be answered without the name of the maker and the serial number.
12 Ga Magnums were never made with a gold trigger in Belgium (with one exception in the 1980's on a special order) The Gold trigger was reserved for the light 12, Sweet 16's, the light 20 and the Mag 20. When Browning came out with the Magnum 12 model in 1958, it was essentialy the same gun as the Standard weight 12 ga, but fitted to shoot 3" shells vs 2 3/4. Up until 1967, only the lightweight guns had a gold trigger to signify the "light gun" version. Lighter guns were more desireable, and the gold trigger was special. Browning also introduced the Light 20 ga gun in 1958. Thus another light gun had the gold trigger. Magnum 12's would not. Also, the Mag 12's were advertised as the pinnacle of Waterfowl guns. What every shooter wanted in the duck blind. The gold trigger wouldn't have gone over very good. In 1967 When the Mag 20 was added to the line, Browning broke the pattern and put a gold trigger on this model as well.
Impossible to answer without the serial number and maker name
The Marlin Model 3000 was the chain-store version of the Model 336. They added a gold trigger, gold bead sight and have no checkering.
The trigger is just a gold looking plating that is applied.
