Authentication and grading
PMG (Paper Money Guaranty) and PCGS Banknote dominate paper money grading. Heritage Auctions handles most of the high-end market. Always buy graded for any note over $1,000. Counterfeit “rare” notes are abundant. Edge integrity, paper crispness, and ink density matter more than they do for coins.
