The product is a set of circulated/uncirculated $1 Federal Reserve Notes with fancy serial numbers, specifically from the year 2021. These notes are from the United States and are uncertified. The grade designation for the notes is apparent/NET, indicating that they have not been officially graded. This unique set offers collectors the opportunity to own multiple denomination paper bills with distinctive serial numbers from the Federal Reserve.
They are crisp and maybe uncirculated. I am not an expert.
