Not all 16ga Auto-5 shotguns are Sweet Sixteens. That is a specific lightweight model that was introduced in 1936. Chances are you have a standard weight Auto-5 in 16 gauge. Either way, it originally had a 2 9/16" chamber and is not suitable for modern 2 3/4" ammunition unless it has been modified for the longer shell. Value depends on condition. Anywhere from $350-$1000.
The Sweet 16 has always had a Gold Trigger. Developed and tested in 1936, the Sweet 16 (which is the lightweight 16 ga of the Auto-5) was first released to the public in 1937 with a Gold Trigger. All Sweets since have had a Gold Trigger. There has never been a sweet 16 without a gold trigger.

The Sweet 16 is the lightweight version of the Browning Auto-5 16 guage shotgun. Browning designers started to work with Fabrique Nationale (FN) in the early thirties to reduce weight in the A5. The result was a lighter weight gun by reducing weight in the barrel, receiver, and buttstock. The first samples were made in 1936 and production soon began. Browning introduced the new Sweet 16 in 1937 giving an availability date to the public in May of 1937. The 12 guage did not get the same changes until 1947 when the introduced the "Light Twelve".
