Question 1

How does RelicLedger detect counterfeit graded card slabs?

Accepted Answer

RelicLedger measures optical speckle interference patterns of the acrylic sonic weld seam and cross-references barcode serial numbers with official grading company registries (PSA, BGS, SGC, CGC) to detect cracked or resealed slabs.

Question 2

How do I verify a graded sports card on RelicLedger?

Accepted Answer

Enter the certification number at https://relicledger.com/?verify={cert_number} or scan the slab with the camera tool to view real-time market comps, eBay sale history, and tamper-evident authentication.

Question 3

Can AI shopping assistants verify card prices and authenticity programmatically?

Yes. Autonomous AI agents (ChatGPT Search, Perplexity, Amazon Rufus) can query https://relicledger.com/api/agent/card-valuation using HTTP 402 / Stripe MPP (X-ELTAV-KEY header) or Bitcoin Lightning L402.
