2006 twenty dollar Federal Reserve Note in Gem CU Uncirculated condition, A1, Federal Reserve Bank of Boston, and with macro front plate digits indicating this to be among the first of the SOI printing.  This note has razor sharp edges, corners, great inks and paper, gem centering, and punch through embossing which is shown in the last photo.  It's the reason I put them aside years ago.  This is the sixth of six consecutive notes listed.  Pictures show exactly what you are getting.
