Your pictures leave a lot to be desired. I don't see the doubling on your coin that compares with this: http://coppercoins.com/lincoln/diestate.php?date=1966&die_id=1966p1do001&die_state=mds Could just be the grainy pictures though.
The CHERRY PICKERS GUIDES list values for higher grade error and varieties. Whether you can get those prices I couldn't say. I consigned several at a local coin shop. One sold the other is still there. Like all coins the lower the cost the more potential buyers there are. The one that sold was fifty dollars. The one that is still there is marked $200. good luck.
Yeah pictures suck, I nee better magnification equipment and a new phone. Compared mine to the pictures and found a lot of the markers shown. One or two are hard to tell because I'm using a weak jewelers loupe and have poor lighting, also the coin is a bit worn. Not sure what's wrong with his lip, I noticed that too. Almost looks doubled up close but could be Mint Damage?
This is the liberty on my coin compared to a PCGS gradede graded example. Among other similarities, it looks pretty damn close
That's not where the doubling is...You need decent shots of IGWT and the date. Also, close doesn't count. It either is or it isn't. Based on pictures provided, I say it "isn't".
