Looks like a die crack in front of Abe's nose. If he tilts his head back a few inches he'd be snorting something.
Though I might not be actively looking as much as I used to, I will never stop saving wheat pennies I happen to come across lol. I actually found one on the ground in my bank's parking lot this year. Not counting what's in my Lincoln cents album, I have about 3 rolls and counting of wheats now.
Finding a 1952 cent in circulation doesn't seem like much until you consider the age. It's 72 years old. When I was a kid collector in the 1960s, that would have been like finding a late 19th century Indian Cent in circulation.
