To start off the 1961 Topps Card are great, just the condition of the cards is the question with the cards near mint the Maris Cards could be worth around 300, Mays around 100, with the Koufax around 30 since.
The Pujols Rookie is going to be getting higher in value as long as he keeps up his pace. McGwire cards were just in a downfall after his record breaking season and only see them going up a little if he makes the hall. And the same goes for Griffey and Bonds Cards. The value of cards are really priced on the value the cards sell at. There are so many rookie cards floating around of Griffey, Bonds, and McGwire the value of the card will go down. The Clemens and Ripken are only going to get better, so thats good. Remember though the condition of the cards have to near mint to perfect for cards to be valued now, anything less really it is just a item for you to have.
The Swatch Card of Maris and Mantle is awesome I am jealous as hell, that cards and that cards is worth more then the 61 cards put together and for the Clemens well I bet ya some people can even put a price on that since it is a 1/1. I am a big collecter and have some 1/1 cards and one was of Chipper Jones and sold it for 350 bucks, Awesome stuff though man.
