2004 E-X Clearly Authentics Emerald Dual #SLBG Dan Marino & Jim Kelly "1 of 1" Game Worn NFL Logo Shields BGS NM-MT 8.5. Two of the all-time great quarterbacks rest side-by-side as Marino and Kelly grace this stellar card. Each side has the NFL shield from each player's respective jersey perfectly complimenting the photos. Sub-grades rate: Centering 9.5, Corners 8, Edges 8.5, and Surface 9, for a strong NM-MT+ 8.5 overall. The only one of its kind in existence, back is numbered 1/1 and vouches for both jersey swatches as game used. As divisional rivals with the Miami Dolphins and Buffalo Bills respectively, Marino and Kelly were no strangers on the field and theirs was always a marquee matchup of two of the sport's top gunslingers.
