Hi there,

I wish I was burdened with such a huge collection, haha
I would have a hay-day going thorugh all those goodies!

Organizing the cards on this site will give you an estimated value of the collection.
You must take into consideration that people have likes/dislikes when buying in bulk.

If you have $1000 in 5-75 cards, realistically you'd be lucky to get $20 for them.
Some people build sets but most are out for player/team collections (mainly pack pulled autos/GU)

Pesonalized Autos are a tricky subject.
They could possible get attention if they are hand signed autos.
They will get more attention if there's physical evidence of their authenticity.
Auto cards made out to individuals (such as your father's) probably won't get much attention.
Best bet is to keep them as sentimental value. Put them all in one big frame.

As for the other cards, it's best to put them in class types opposed to teams.
(Autographs, Game Used, Parallels, Inserts, Base, etc.)

Unload all of the low end cards as one giant lot and consider yourself lucky if you sell it.
Let me know if you need help as I've had success selling lots like this in the past.

As for the mid-high end cards you are then provided with options to sell individually or as smaller lots depending on your target audience.

Hope my insight helps a bit, cheers!
