The last bag I got from my Credit Union before everything went south was interesting. When I got it home I realized that a lot of it was uncirculated 2018 P pennys, and figured it would be a waste of time. I got the usual few wheats and other junk, but I looked at one of the 2018's and saw a die crack between the W and E that went into Linoln's head so I started looking at the 2018's closer. I ended up keeping almost 250 pennys with the die crack. I found more but kept the best looking ones. I haven't got a clue what I am going to do with them, but for now they are in tubes. I just thought I would share this since it was an interesting find. The picture is a little blurry, but you can see the crack.
Many of them probably came from the same die. You could pass some time trying to trace the crack from early to late stages. I've done that a time of two.
