How about a pic of the entire coin, both sides? Is it a 71, 81, or 91? What is so special about it, that you want to sell it on eBay?
Machine doubling. Be sure to list it as such. Calling it a doubled die will cause you nothing but grief. Worth whatever you get for it.
It's neither a 2001 or a 2011. And the "head crack" that I think you are referring to is PMD. Looks like marks from the reeded edge of another coin.
Look at the first picture that is posted by OP. under the words 'IN GOD' you can see the very tip top of the number one. It is the wrong shape to be the top part of a 2.
List is as machine doubling. The profile doubling makes it a bit better than most MD you see. Someone will probably pay a few dollars to own it.
As others have stated, it's MD. I agree with starting it at $.99, listing it as Mechanical(or Machine) Doubling, and let the bidding take it's course.
I Think you can list this as Obverse DOUBLE PROFILE...Like an 1966 Kennedy Double Profile.. That's all. http://www.ebay.com/itm/1966-KENNED...77?pt=Coins_US_Individual&hash=item53e550d0d9
