100-8000 USD depending on EXACTLY what you have and its condition.
300-500 depending on what type it is. Trap guns fetch more.
Between 400 and 500 dollars, depending on condition of gun. 1980 brand new still in the box
Not sure what they are worth but I look at one at my local gunshop today and they are asking $3,995.00.
150 mint condition
From your description.The shotgun would be worth between 375-475 dollars,on today,s market.
1100 is a Remington, not Browning.
The 1100 designation for a Remington shotgun is the model number. Remington makes the 1100 model in a trap version and a field version.
with the L prefix to the serial number,this would indicate that your model 1100 Remington shotgun was made in 1991.
Visit the Remington web site.
Depending on condition, expect $500-$800.
The Remington Model 1100 shotgun is still in production, hence it would be worth no more than list price - and probably less, if it has been used at all.
