Black back notes are some of the rarest and most desirable Silver Certificates ever produced by the United States. This note is not only rare but it carries a significantly important designation that makes it stand out to most other $20 Black Back Decatur notes. This is one of the few examples graded with the “Premium Paper Quality” moniker. And when it comes down to quality and value, PPQ is a must! One look at this note will reveal why PCGS awarded the "Premium Paper Quality" label. With its bright color, original embossing, vivid eye appeal and light handling throughout, it was an easy decision to make. With only 3 examples finer with the PPQ designation, finding a nicer example at this price point would be almost impossible to do.
