In 2009 the Finest set included 150 base cards and another fourteen rookie autographs cards. The interesting thing with the rookie autos is that the autographs were on letter patches instead of on a plain card. There were letter patches for each letter of the player's last name and some collectors went for each of the letters. I got off easy and didn't have to go for any of the letters since no Cubs were on the rookie list.
As far as the base is concerned, there were eight Cubs included. Your numbers go up when you win the division two years in a row. In the five years following this set, there are only twelve Cubs total among the five. When you finish at the bottom of the division for five years in a row, your numbers go down.
The eight Cubs in the set are the most likely eight to be chosen. All were major contributors to the success of the 2008 team.
