Is the thing jetting out raised or indented ? The whole extra ear thing is hard to spot . I looked at some examples again and I'm on the fence about that . I'll wait for someones else opinion, ok?
I don't see anything unusual on the ear of the first coin. The 7 in the date of the 1967 coin is simply where the coin took a hit in that area. It's rather interesting in way it pushed the metal aside, but unless I am much mistaken (and I don't think I am), that's post-mint damage and not an error. Good closeup pics, though, BTW.
The ear looks like it has damage and a vase of NAV Doubling. The 1967 took a hit and the word LIBERTY has been damaged. All three are worth face value.
