The Florida Marlins are off to an 11-1 start. If you want to know who to collect the main players would be Hanley Ramirez, Emilio Bonifacio, Dan Uggla, Cameron Maybin and Chris Volstad. Also good on the Marlins would be Ricky Nolasco and Andrew Miller.
The best products to find rookie cards in would be Bowman Draft and Bowman Chrome. You will also find some on Chris Volstad in 2005 Topps Updates.
Look through ebay to find some of the best prices as you can usually get 1/2 off Becketts price guide. You can also find similar prices at sports card shows.
