I have never dealt with paper currency I am still learning about the coins but today at Walmart I got 4 bills in my change that caught my eye. The first one was a $20 bill with what I think is a binary(just learned that word today lol) serial number. The other 3 are $1 star notes in sequential order. The star notes seem to have some ink issues but I am not sure from what or how. Some look like fingerprints and ink mixed with hair. Then from the back I noticed the serial number coming thru the paper of all 3 bills. You can feel it as if it was brail on both sides. Is this normal? Are they considered errors?
Nice finds. I believe member @cashhound collects $20 notes with similar serial numbers. The fingerprint looking stains are not common but show up from time to time, mostly $1 notes. No big deal.
Do you know what the ink marks are from on bottom of bills. Theres like 4/5 spots along bottom of bills and they line up when all 3 bills are together...and any insite on serial numbers that are coming thru paper and feels like brail on both sides?
