CoinVault AI

The Smart Numismatic Appraiser in Your Pocket

Identify rare coins, estimate Sheldon 70-point condition grades, spot striking errors, and discover fair market values verified against live auction sales records—stored securely in your private cloud vault.

✔️ Conforms to PCGS & NGC criteria • Live auction records integration.

The Challenge vs Solution

Figuring out what you have is daunting.

❌ The Problem

Whether you’ve inherited a family collection, found an unusual coin in pocket change, or bought an estate lot. Printed price books are out of date, online forums are inconsistent, and professional third-party grading slabs cost $50+ per coin with weeks of turnaround time.

💡 The CoinVault Solution

CoinVault puts an expert numismatic eye on your smartphone. Take two crisp photos—front (obverse) and back (reverse). The optical analysis engine examines high-point wear, portrait details, mint marks, and striking varieties, then scans live global auction records to provide an instant identification, Sheldon grade estimate, and transparent market valuation range.

Core Feature Pillars

📸 Dual-Side Optical Inspection

Full 360° Visual Analysis

Uses guided circular reticles and mobile macro camera support to capture legends, mint facilities, high-relief strike depth, and edge rims.

⚖️ Sheldon 70-Point Grading

Condition & Wear Estimation

Delivers detailed grade assessments following the standard numismatic 70-point Sheldon scale (from Good G-4 to Mint State MS-65+).

🚨 Striking Error Detection

Rarity & Variety Spotter

Scans for doubled dies (DDO/DDR), repunched mint marks (RPM), off-center strikes, die cracks, and clip errors that dramatically multiply value.

📈 Live Market Auction Search

Real-Time Price Discovery

Rather than static estimates, valuations are verified against current auction sales across Heritage Auctions, PCGS CoinFacts, NGC guides, and marketplace transactions.
