The card redeemable for week # 3 in the 2012 Topps Home Run Legends Prime 9 program is Hank Aaron.
From now through early April, Topps will announce a “Prime 9 Player of the Week”. Collectors holding the corresponding Prime 9 Redemption card for that week can bring the card into their participating local HTA store and redeem it for an exclusive limited edition Topps Chrome Refractor.
Redemption cards can be found in 2012 Topps Series One Hobby packs (1:18) and Jumbo packs (1:5). Each card is denoted by a Week number (1, 2, 3, etc.).
The checklist so far:
Week 1 Willie Mays
Week 2 Babe Ruth
Week 3 Hank Aaron
