The following are the $20 Confederate notes in my collection. The first two are from 1861 and the 3rd is a more common 1864 issue. The second twenty shown (T-20) is in uncirculated condition and authentic. Counterfeits of this note are also available to collectors and generally sell for about a hundred in mint condition. Authentic notes of this variety are worth considerably more. Below the vertical Twenty on the right side of the central vignette is the number 7. The counterfeited notes generally have a plate number of 6, and sometimes 9. To easily distinguish a genuine from counterfeit T-20 note however, simply look at the faces of cupid and hope on the notes. The authentic ones have slight smiles whereas the contemporary counterfeit ones have frowns on their faces (Source: Heritage).
