I found this today while searching through uncirculated rolls of 2011 pennies. Is this a form of cud or cracked die? He looks like he's sneezing but, then there are a lot of different issues with the obverse and reverse. Is this worth slabbing?
I would make a big deal out of this and call it the famous Lincoln sneezing cent ) You never know you might make a buck or two out of it And yes gas bubbles
I had a 1970 D Penny that looked like Abe was sneezing...posted it under Coin Chat couple of weeks ago for fun.
