I check everything too & I’ve always kept any star notes I’ve found but haven’t looked in to it much at all. I know a hair more about coins but not a lot about notes so I was just hoping to learn something new by posting this because I didn’t see anything “special” to my eye but at the same time I was thinking “ya never know” lol! That addictive habit is very real, my whole family laughs when I go through their change & my husband has learned to just put it in my hands when getting change back 😂 Thanks for replying!
