What to expect

Straight answers
about the grade.

What the estimate is good for, and where it stops.

Designed for ±2 points

The model is built to land within two Sheldon points of a PCGS or NGC grade on clear photos of common U.S. coins. That is a design target, not a measured guarantee — we say so.

An estimate, not a slab

Only PCGS, NGC, ANACS, ICG and PSA certify coins. Use the estimate to decide whether a submission is worth $50–$120, then let them grade it.

Private by default

Your photos and reports are not published unless you choose to share a report link. Payments, if you upgrade, run through PayPal.

Common questions

Frequently asked.

CoinGrader AI is designed to land within ±2 Sheldon points of a PCGS, NGC or PSA grade on clear, well-lit photos of common U.S. coins. That is a design target: we have not yet published a measured validation study, so treat the result as an estimate. It is accurate enough to tell an MS62 from an MS65 decision, not a substitute for certification — only PCGS, NGC, ANACS, ICG and PSA issue certified grades.
Professional coin grading costs $20-$300+ per coin depending on the service level. PCGS charges $23-$300+ (Regular $40), NGC $20-$175+ plus a $10 handling fee, and ANACS $14-$150. Total real cost including shipping and insurance is typically $50-$100 per coin for regular service. AI pre-grading is free and helps you avoid wasting $50-100 on coins that won't profit from certification.
A coin is worth grading if certification will add at least 3X the total grading cost in value. For example, if grading costs $60 total (fee + shipping + insurance), the coin should be worth at least $180 more when certified. Use our free AI pre-grading tool to estimate your coin's grade and calculate potential ROI before spending money on professional grading.
Choose PCGS for premium U.S. coins worth $500+, key dates, or coins you plan to sell at major auctions - PCGS commands 5-10% higher market premiums. Choose NGC for value-conscious grading, world coins, modern bullion, or personal collections - NGC costs $5-10 less per coin and has faster turnaround times. Both offer similar grading accuracy and quality.
No. AI coin grading provides pre-grading estimates for educational purposes only, not official certification. Use AI grading to pre-screen coins before submitting to PCGS, NGC, or PSA - this helps you avoid wasting $50-100 on coins that won't grade well or profit from certification. For official certification and maximum resale value, you still need professional grading services.
Our AI works with most U.S. and international coins including Morgan dollars, Lincoln cents, Kennedy half dollars, Buffalo nickels, Mercury dimes, Peace dollars, and modern bullion coins. Best results require clear, well-lit photos of both obverse and reverse. The AI is trained on PCGS, NGC, and PSA standards and provides estimates based on professional grading criteria.
AI coin grading takes under 60 seconds with instant results. Professional grading services take longer: PCGS (5-65 business days depending on service level), NGC (3-60 days), and ANACS (5-40 days). Most collectors use regular 30-day service at $30-35 per coin. Add 1-2 weeks for shipping each way, making total turnaround time 4-8 weeks for professional grading.
