i have over 200,000 cards i need to sell. listing in organize takes a long time to price, grade, compare, find and add each card. i have boxes and binders full of all types of cards mixed together don't have a clue as to what all i do have. some cards i have for example upper deck vs upper deck electric look the same but have different prices. this happens a lot with different types of cards. any idea as to how to list them correctly and grade them since they have not been graded by a grading company but just by what i think by appearance and condition compared to others i have seen on the web. a lot of the cards don't have pics to compare with so that i know it is in the right class.
is there a way to list all of them then group grade, identify and price. or what suggestion do you have as what would be my best options

i have learned the difference between upper deck vs upper deck electric {says so on card} after i was going through my cards as i found many of both even though the beckett pics look the same when you click on them at least the ones i checked.
have found a few other things out in my searches also about gloss more valuable than flat in most cases.
i even check the market place on some cards and some of them were off also.
. anyone know a good source to compare cards to make sure i list correct, please advise.
hope they update their pics soon and ad an icon noting pics.

TrollandToad.com sells gaming cards daily so it'd be a good source for pricing.
