To be honest, I couldn't tell. But I'm willing to bet that you'll have to keep your +9 treasures to unlock the Cookie. But once you unlock the cookie, you can just sell them and it won't lock back.

Also I checked back my treasure and I didn't know I have 22 +9 treasures. 17 of them are S-grade. Wow...
