I am valuing each card at $2.5. Some may worth less and some may be more. The two UD MVP cards are around $5 and $8 median sale price on ebay. There is one set of duplicates.

I do not believe any of these cards are psa 10 material. Maybe some 8 and 9. The three cut above cards have wear at the top. 1990 nba hoops card has wear on bottom right. The catch 23 card has wear on top left. The two NBA Finals Shots cards has slight corner wear. The 1999 upper deck card ( last picture) has wear on top left. Most other cards are in great shape.

I took a picture of each individual card so you can examine. All cards will ship in penny sleeves. If you need more pics I can provide. $5 ground shipping and will ship next business day.
