$75 to $250 depending on condition. Express do not get the value of the wingmasters.
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.
$200
See related link.
$200-$250 if better that 90%.
$139.95
100-400 USD
Probably around $250 used.
The serial number is located on the left side of the receiver, towards the rear, just above the trigger.
