More topps Update

Bought two more packs and am a little bummed as I received three doubles out of the sets.

Pack No. 3 WalMart 1951 Topps Blue Back Insert Cards
12 Cards
Topps Million Card Giveaway TMC-25 Mickey Mantle
Topps Attax Josh Hamilton - Texas Rangers
US-23 - Andy Pettit - P - Yankees AL Allstar
US-46 - Colby Lewis - P - Rangers
US-65 - See You in September (Checklist 9 of 10)
US-69 - Lance Cormier - P - Rays
US-162 - Hong-Chih Kuo - P - Dodgers
US-180 - David Wright - 3B - Mets NL Allstar
US-230 - Robinson Cano - 2B - Yankees AL Allstar
US-275 - Hong-Chih Kuo - P - Dodgers NL Allstar
US-277 - Micah Owings - P - Reds
US-279 - Hanley Ramirez - SS - Marlins Home Run Derby

I found it a little odd that this pack would have two cards for the same player in it, Hong-Chih Kuo. I do like the Mickey Mantle from this pack as I try to collect any player wearing the number 7.

Pack No. 4 Target 1951 Topps Red Back Insert Cards
12 Cards
TR120 - Curtis Granderson - CF - Yankees
VLC34 Vintage Legends Mike Schmidt - 3B - Phillies
Topps Attax Kurt Suzuki - C - Atheltics
Topps Attax John Lackey - P - Red Sox
US-66 - Ronnie Belliard - 2B - Dodgers
US-69 - Lance Cormier - P - Rays (Double)
US-101 - Jake Westbrook - P - Cardinals
US-162 - Hong-Chih Kuo - P - Dodgers (Double)
US-168 - Wilson Ramos - C - Nationals
US-212 - Mitch Talbot - P - Indians
US-273 - John Jaso - C - Rays
US-275 - Hong-Chih Kuo - P - Dodgers NL Allstar (Double)
US-319 - Josh Tomlin - P - Indians

I found it very odd that this pack would have the same two cards for the same player, Hong-Chih Ku, as well as a double of the Lance Cormier card. The one saving grace for this pack was the Mike Schmidt legends card for my Phillies collection and the Turkey Red card for my Yankees. Any body else had this happen?
