End Game Weapons

Is there a base price for end game Weapons (green). I am new to this site & thought maybe I can sell some of the weapons I have gotten from beating the game. I have several different kinds so was just wondering if there is a base price. thanks

as they are end-game they are incredibly common

so pretty much 3-4k each regardless as skin aent great,

simple as that they are very common therefore not earning a great value
