Things You'll Need
Instructions
Before you try and sell if they are sports cards, organize them into complete sets or as close as possible. Most buyers like complete sets not random individual players.
Know the value of your items. Look up prices on online pricing guides such as Beckett or Tuff Stuff. See what others are asking by googling or visiting sites.
Great individual cards are okay to separate from the rest as these will be easier to sell. If you separate them these cards should be valued at close to $100 or more. Otherwise, don't bother.
You can try and ask full price but if you do you will never sell them. Ask for a quarter to a third of the value.
Avoid grading unless you want to reinvest in your collection, as grading is not cheap.
The best way these days to sell your collection is in a garage or yard sale. Set a reasonable price for your items and hope for the best.
After you have tried the yard or garage sale now is a good time to try the local flea market or card dealers. That is if they are buying at all these days.
Last, is the internet. There are a handful of sites where you can display your items/collection and sell them for a fraction of their actually cost. EBay, Amazon, Sports buy, Craigslist, and the list goes on and on. Be careful though as the net is full of scams and con artist.
If you have no luck with any of these, your best bet is to just hold on to them a little longer until our recession,(mini-depression) gets better.
Good luck, hope this helps you make some extra money.
