They Help get you the last Limit Break on your SR and SSR Kamihime. The Silver is for SR and Gold is SSR.

Don't worry about grimoires. They're used to bring your SR/SSR characters to their final limit break, so you can reach max level. They're much easier to obtain in raid events than standard events, so you'll naturally get some as you play this game and participate in the events. For standard events just worry about getting a copy or two of the SSR weapon and the SSR eidolon. They're more important early on.
