I am new at the paper money aspect of collecting or errors. I got some change back and happened to notice that the left serial number had the 3 that looked misaligned lower and the 7 was thicker and taller than the other numbers on this dollar. I know this is not common, but is it an error worth keeping? Thanks.
Hey I have a question, I have a couple of $20 Bills with the right side stamp like an inkwell contamination is this anything worth keeping?
