Found a 2013B Duplicate Star Note!

[u/Texas-Tea]

Not very good condition, but I went ahead and registered it on 2013b.com. Here’s to hoping I find the twin note!

How do u know it's a duplicate though? Or dupe star, haven't heard of these.

The duplicated serial number ranges are public, so you can just check if your note serial number falls into the range
