Do you happen to have a full pic.? In order to get a better view. Also, all you need is a 10x loupe. Thanks.
Whatever it is it’s affecting both sides of the coin. From your first photo it looked like adhesive on the coin. From these recent photos I think there was something on the die and grease is what comes to mind. Thank you for the extra photos.
When the letters and digits are missing like that it is from a grease filled die that wasn't completely cleaned out. I'll try to find mine and post a photo. I'm too lazy to take it out of the flip. I got this when they first came out in circ and at first, I didn't understand why it was in such worn shape.
Thanks everyone. That's what I thought, I just like to run it by you all. Nonetheless, I think it's a cool find.
