The best way to sell baseball cards is FIRST determine if the card you have has any value at in the current market. Beckett Baseball is the industry standard on valuing baseball cards.
So now you have determined “Hey, I have a Nolen Ryan rookie!!!”
If you want to see on email and make top dollar, it need to be professionally graded. PSA and Beckett are the 2 largest independent grading services. They are graded from 1-10. 10 being the best of the best and are not given out freely.
When it comes too sought after rookies and low run cards. This is the only way people will buy them online. That way they know what you are getting and can be validated on the PSA web site.
Highly graded cards can go for many times the book price.
This is for the serious collector.
You can also just sell them on Ebay in lots or singles but if not graded, be prepared to get 25-50% book if you are lucky.
Otherwise – take the lot to you local card show and ask him what he will give you – just be prepared for “Not much”
I have approx 500K baseball cards in my closet that I havent looked at in 10 years. Maybe one day my son will be able to buy a GT2 with them.
