Game cube / Game contoller memory, what grade is it?

Someone is giving me some memory cards for a game cube and some for a PS2 I think, what sort of scrap is this? Does it grade like RAM memory?

Thats a good question. they are like sandisk cards really so im not sure if they would be high grade. Im thinking mid grade but easy or someone could answer better.

They have about six or seven gold fingers on the board where it plugs into the cube. I'm thinking cut these off and add to the finger pile.
