Value depends a lot on condition. Most of those big boys have been rode hard and put away wet.
Go ahead and list it on eBay and see what shipping will cost.

I’m assuming it is not damaged.
See what somebody will charge you to build a properly reinforced wooden crate on a pallet that can be handled with a fork lift. Then build that into your ebay listing.
Go with a low starting bid like $999 and see what the market will bring.
Good luck
If you want to only sell locally, take your time and advertise everywhere you can and wait for the right buyer to show up with the right equipment.
