the rumor is any serial number on an 870 express ending with an M means its a magnum. I have one I bought in about 1987 and have shot thousands of three inch shells through it.
D081337n
$75 to $250 depending on condition. Express do not get the value of the wingmasters.
$200-$250 if better that 90%.
100-400 USD
I would like to know the value of Remington 44 magnum and the model 1742. and the serial number B7346828
Check the Remington Society of America, date barrel codes and location. http://remingtonsociety.com/rsa/questions/barrelcodes
The serial number is located on the left side of the receiver, towards the rear, just above the trigger.
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.

You can call Remington at 1-800-243-9700 and go thru the menu selection. One of the menu options is to request information on your Remington based off the serial number. You read off your serial number and the guy looks up in the database the year the gun was made and what the original barrel was for that gun (if gun had barrel options like shotguns do).
Perfect condition, 28" BBl with Rem chokes, $350.00. Short rifle sighted slug BBl with no chokes $290.
