• Live valuation — comp-backed values for every graded card
• Which grader pays most — PSA, BGS, SGC or CGC, and what you'd get selling today
• Concentration & liquidity — see where risk is hiding
• Insurance-ready — broker schedule and claim pack in one tap
• Scan — point your camera at a slab to add it instantly
• Sign in with Apple — one tap to get started
