Looks to have sold at least twice at public auction. REA gave the opinion that the card was trimmed when writing it up for their auction in 2008.
Graded NM-MT 8 by Global Authority. This is a very attractive highly graded example of one of the four classic poses of Ty Cobb from the T206 White Borders series. The T206 Ty Cobb “bat off shoulder” pose is one of the most popular of all T206s, and one of the most highly regarded of all Cobb cards. This example has a particularly bold image, which really "jumps" from the card, and extremely vibrant colors. In our opinion, this card has been trimmed, though someone else could have a different opinion. Perfectly centered. This is very sharp-looking card; extremely clean, both front and back, with four razor-sharp corners. Sweet Caporal advertising on the reverse. Our consignor paid $3,700 for this card at auction a couple years ago (in 2010). The SMR value for a PSA NM-MT 8 is $17,500. Reserve $1,000. Estimate (open).
