New Member Looking For Advice

[MTBoiler]

Ok, Recently 'picked up' my old cards from my parents house and looking to sell them if I can.
I have a lot of cards...well relatively speaking. I have 1500 baseball cards from the 70's, 1/3 are 1975. I have another 700 plus cards from the 80's, I know they are probably worthless. Countless Ryan's, Bench's, Rose's and Aaron's, plus a Robin Yount rookie card that I had no idea I had! I have about another 200 plus cards that are not topps cards too.
I have 500 football cards from the 70's, including Roger Staubach rookie card. I have 250 basketball cards from the 70's too!
I spent some time 'inventorying' them by year and make, almost everything is Topps. I then went thru and pulled the pricier cards and put them in hard sleeves vs penny sleeves. Everything is now in a penny than depending on who the card is, a hard sleeve. I am sure there are dozens of cards I missed too because it has been a while.
So, do I sell the whole things as one big lot? I was thinking about sending them all the an online card house until I read that you send them the cards and they send you a check without any consideration of whether you like the price or not.
My second thought was to break them into lots and sell them on Ebay? I figure I could sell the 16 1972 football cards I have, one being a very good condition Roger Staubach, as a group.

Thoughts? Suggestions? Comments?
Thanks in advance.

Sell the higher end cards (stars and rookies) as individual cards. then sell the commons etc, as lots either by year or sport

if they are common cards selling on ebay might be an
option
you might do better if you sell in certain size lots.
better than 1 big lot..
and it depends on shipping also..

Sell the better cards as singles and do lots with the commons is the best idea and good luck!

i've never sold a card on ebay or any online community but ebay is probably a good channel, unfortunately it has fees. I've only bought cards on ebay. You did not mention whether you are going to stay in the hobby and collect. But you did come to SCF so maybe as one member suggested --try sell them here. Either way, good luck if you just ant to flip your collection.
