I think it is interesting that some baseball sets may be a favorite to one person while another person may completely dislike the same set. One baseball card set that has always been a favorite of mine is the 1975 Topps set. This set features bright colors leading to a party like atomsphere. The 1975 Topps set is a favorite of many people.
Another set that has been a favorite of mine is the 2002 Upper Deck Piece of History. This set has a very serious and professional look. It is a small set with just 90 cards in the base set with 42 additional cards that are a subset of rookies called 21st Century Phenoms. The first 90 cards in the set feature a nice mix of current (2002) players and some old timers. There are 10 short printed cards among the first 90 cards.
The Phenoms sub set features 42 different players each with 3 serial numbered cards. Two these phenom cards came in hobby boxes and were numbered to 625. The third card came in retail boxes and was numbered to 950.
To build a complete master set of the Piece of History set, one must collect the entire 90 cards of current and old timers including the 10 short prints. Then to collect all of the Phenom cards one must assemble an additional 126 cards.
Of course, I was originally just collecting the Cubs in the base set. This include 4 cards including one SP. The Cubs in this set include Billy Williams, Andre Dawson, Ernie Banks and the SP, Sammy Sosa.
As time goes on I will talk more about this set. It also has several interesting insert sets and jersey -jersey/autograph variations of the insert sets. It is still possible to get reasonably priced boxes of these cards.
I currently have 67 of the 126 different Phenom cards. I am actively working on the 59 Phenom cards that I am missing. I plan to use this blog to track my progress on completing the entire Phenom set. All in all, the 2002 UD Piece of History set is a fun and challenging set to collect.
