When selling the Rare/Purple Mind Resets the items are supposed to sell 10k Credits and 3 Fate. While they do return 10k credits when sold, they unfortunately do not give you any date.

I double-checked by selling a second Mind Reset, and sure enough, my fate did not increase at all (I started with 111 and after selling two of the consumables, I was still left at 111 when I should have ended up with 117).
