Marlin 336 dark 30/30 value?

[syoungs]

I have one of the original marlin 336 dark rifles sitting in my safe, never been shot. I won it in a raffle 5 or 6 years ago. I dont think ill ever use it.
Looks like they sell for 1500-1800$ on gunbroker, that would buy me a rifle I would use for sure...

what should I ask for a unfired safe queen?
