Though virtually identical to the E254 Colgan's Chips issue, the E270 "Tin Tops" cards were inserted into tin canisters of Colgan's Mint Chips and Violet Chips.  The cards are considerably more scarce than the E254 issue, so much so that the entire set has yet to be checklisted as it is assumed that undiscovered subjects exist.  This example, picturing Ed Foster of the Red Sox, has been graded VG/EX 4 by SGC, with light edge wear being the sole condition flaw with the card.
