JK Index × Muse

Your Muse agent runs your collection. You make the calls.

Connect JK Index once. Your agent keeps your cards priced, tells you what’s worth grading, follows Before the Slab events for cards you own, and takes a position when you say yes.

Your Muse agent runs your collection. It knows your cards, live prices and what is worth grading. Before the Slab sits in the middle: a card goes up for grading, your agent briefs you, you approve the call, the grade comes back. Blitz sits beneath it. A Sunday brief, alerts and your positions come back to you.
Example cards and numbers.
