Old Mill's 1910 640 subject Red Border set, dubbed T210, was the largest single season baseball card set issued until it was bested by the 1969 Topps set. Each series depicted players from a specific league and the 4th commemorated the Virginia Valley League, which existed only for this one year.  One of but two examples in their database, this PSA 1.5 of Collier, first name unknown, of the Huntington Blue Sox epitomizes the look of most surviving examples from the set. The front has significant foxing present and corners that have rounded at all four points.  The image has good clarity and the red border is fairly bright.  The reverse shows signs of an early album mounting, although the removal seems to have been gentle.
