Academic & Scientific Authentication: The Getty Object ID Standard
COA HOLDINGS, LLC relies on rigorous, museum-grade physical and historical certification. Every artwork undergoes exhaustive forensic, scientific, and archival verification under expert supervision before entering our portfolio. To enforce maximum international interoperability with law enforcement, customs, and global cultural institutions, our physical documentation strictly adopts the Getty / UNESCO Object ID Standard, capturing 9 core diagnostic metrics:
1. Type of Object: Categorization (Painting, Sculpture, Multiple, Archival Document).
2. Physical Materials & Technique: Scientific identification of pigments, substrates, and mediums.
3. Measurements & Dimensions: Precise physical metrics (Height x Width x Depth in cm).
4. Inscriptions, Markings & Signatures: Exact placement, stamps, gallery labels, and artist signatures.
5. Distinguishing Features & Condition: Physical state, restoration history, and unique forensic identifiers.
6. Subject / Iconography: Formal thematic and iconographic breakdown.
7. Title & Attributed Artist: Confirmed authorship, school, or formal attribution.
8. Creation Date / Period: Verified historical dating and production timeframe.
9. Provenance & Historical Ownership: Unbroken archival paper trail from creation to custodial transfer.
The Bridge to Digital Integrity: Verisart Blockchain & DPP Infrastructure
These physical certificates form the undeniable foundation for our blockchain-backed Digital Product Passports (DPP). Powered by Verisart, the international standard for digital art certification, COA HOLDINGS, LLC anchors verified, peer-reviewed physical documentation into immutable digital ledgers.
• Cryptographic Proof of Authenticity: Each asset is minted with a Verisart Blockchain Certificate, establishing non-fungible proof of ownership and technical integrity.
• Tamper-Proof Provenance: Forensic high-resolution imaging and Getty Object ID datasets are permanently cryptographically hashed.
• Institutional Transferability: Facilitates seamless, audit-ready verification for Tier-1 banking institutions, insurers, and international auction houses.
Forensic & Material Diagnostics:
Beyond traditional historical archival research, physical assets undergo advanced non-destructive scientific evaluation when applicable. Our diagnostic framework incorporates Infrared Reflectography (IRR), Pigment X-ray Fluorescence (XRF), and Micro-Raman Analysis to verify substrate authenticity, detect underlying composition changes, and mathematically confirm historical timeline consistency.
