We get this a lot, and the information below works for just about anything you have and not just baseball cards
This is all my opinion and what I have seen for the past 10+ years I have been selling items.
Aprraisals on collections are a thing of the past. The only true way to know the true value of your items is to look on ebay at sold prices. They are the largest global resell market in the world. The market flucuates on collectibles just like it does on the Stock Market. In sports cards a player could be doing amazing and his cards double or triple in value, while another player gets hurt and he's out the entire season and his cards drop in value.
