The T206 set was and is the most popular of all the tobacco issues. The set was issued from 1909 to 1911 with sixteen different brands of cigarettes: American Beauty, Broadleaf, Cycle, Carolina Brights, Drum, El Principe de Gales, Hindu, Lenox, Old Mill, Piedmont, Polar Bear, Sovereign, Sweet Caporal, Tolstoi, and Uzit. There was also an extremely rare Ty Cobb back version for the Ty Cobb Red Portrait that it's believed was issued as a promotional card. Pricing for the Cobb back card is unavailable and it's typically not considered part of the complete 524-card set. The minor league cards are supposedly slightly more difficult to obtain than the cards of the major leaguers, with the Southern League player cards being definitively more difficult. Minor League players were obtained from the American Association and the Eastern league. Southern League players were obtained from a variety of leagues including the following: South Atlantic League, Southern League, Texas League, and Virginia League. Series 150 (notated as such on the card backs) was issued between February 1909 thru the end of May, 1909. Series 350 was issued from the end of May, 1909 thru April, 1910. The last series 350 to 460 was issued in late December 1910 through early 1911. The set price below does not include ultra-expensive Wagner, Plank, Magie error, or Doyle variation. The Wagner card is one of the most sought after cards in the hobby. This card was pulled from circulation almost immediately after being issued. Estimates of how many Wagners are in existence generally settle on around 50 to 60 copies. The backs vary in scarcity as follows: Exceedingly Rare: Ty Cobb; Rare: Drum, Uzit, Lenox, Broadleaf 460 and Hindu; Scarce: Broadleaf 350, Carolina brights, Hindu Red; Less Common: American Beauty, Cycle and Tolstoi; Readily Available: El Principe de Gales, Old Mill, Polar Bear and Sovereign and Common: Piedmont and Sweet Caporal. Listed prices refer to the Piedmont and Sweet caporal backs in raw "EX" condition. Of note, the O'Hara St. Louis and Demmitt St. Louis cards were only issued with Polar Bear backs and are are priced as such. Pricing is unavailable for the unbelieveably rare Joe Doyle Nat'l variation (perhaps a dozen or fewer copies exist) in addition to the Bud Shappe and Fred nodgrass printing variaitons. Finally, unlike the other cards in this set, listed raw pricing for the famed Honus Wagner references "Good" condition insetad of "EX".
