A look at how the 1969 Topps Mantle became one of the most treasured cards for vintage baseball card collectors.

Trent Grisham led the Yankees to a 10-5 victory over the Twins with two homers, joining Mickey Mantle in historic company.

Cal Raleigh tied Mickey Mantle’s season record for most home runs by a switch hitter with his 54th, and the Seattle Mariners extended their winning streak to nine by routing the Los Angeles Angels 11-2 to take sole possession of the AL West lead for the first time since June.

But there was another home run record set that year — one that is now in its 64th year. The year of 1961 was also when Mickey Mantle hit a career-high 54 home runs. Until yesterday, that was the standalone record for homers by a switch-hitter.
