My $10.00 bill ink error.

These are the unique original different and different individual pieces that I've kept because they was a little different a little odd.....so maybe one day I could learn about them.
Now I can share so maybe I can learn from where they come from and maybe to know where and how they became so unique. Any personal information you may have to share with me I so greatly appreciate it cuz I just love to hear if anyone knows of how and why these things became the way they are I just find it fascinating.
