Gear wear == low dollars. That's been my experience. The right buyer will pay more.
Expect around $250 for a worn but not injured TL. $450-$650 is common for a solid TL without injury.
Big Block early years? Less likely to sell than SBF wide ratio. Narrow body vs. wide? Again less likely.

You're best off posting on ebay and setting reserve to what you're comfortable with.
