I came across this penny a little bit ago, and the date seems to be thicker, especially the "2" and first "0". When compared to other 2006 pennies I have passed, the date seems thinner on those than the one I found. I have seen on Variety Vista and Wexler's coins with similar characteristics, but I was unsure if I have what I was thinking. I don't think it is a doubled die, but I am unsure. I included a close up of "LIBERTY" as well. The last photo is a comparison to another 2006 penny's date. Thanks for looking!
EDIT: Since I cannot edit the original post now, this is the next best thing. After scrolling Wexler's, I believe this is 2006 1¢ WDDO-013 “Best Of” Variety. I could be wrong, but it seems the closest. Mine also exhibits the small die gouge between "IN" and "GOD" seen on the Wexler's post.
