I just purchased two Frank Thomas #1 draft pick cards on eBay. They have both been rated by the PSA and I am going to get them signed this weekend. I was wondering what the difference between a #1 draft pick card and a rookie card is? Is there even any difference? What is more valuable? They are both made by topps and series #414 and both are rated 8 and 9. What will the value price be when I get them signed?
