None that I know of. Unlike the circulation versiona, proof edge lettering is done with a segmented collar which means that each and every coin is exactly the same minus variations in pressure and wear. Some 2007 Jefferson Proof's were produced where the lettering was out of sequence but other than that I have not heard of anything.
The surprising thing to me is I have never heard anything about those 2007 proof Jeffersons with the out of sequence edge since they were first announced. I have to wonder have any of them ever been slabbed for what they are? have any of them ever been sold as the "error" they are? Did any of them actually get out? I don't know. I know they made them, but where are they?
