How We Authenticate:
Initial Review
Our panel of advisors with a combined 200 years of experience initially reviews each item in person.
Chemical Analysis
Our Niton XL5 XRF analyzer assesses the chemical makeup of the item to verify that the material is age-appropriate.
Database Check
We use our extensive internal database of sold items to establish an item's rarity and develop reasonable comparisons.
Certification
These methods collectively enable us to confidently certify an item as authentic. If the item is unverifiable, we will abstain from certification but still provide findings to the owner.
Custom Authentication Decal
Our custom authentication and grading decals include:
Custom QR code for quick access to item details on our website
Unique item number for easy catalog search on our website
Clearly displayed certification and/or grading information
Tamper-proof and non-duplicable labels for added security
Our Custom AGS Grading Method:
100-Point Scale
We use a unique 100-point scale that considers eleven different criteria tailored for various types of items.
Custom Decal
Each item receives a custom printed, tamper-proof decal based on the tier of service selected.
Subscription-Based Catalog
All information is recorded in our subscription-based catalog for customers to review and learn more about the item. The item is also recorded in our comprehensive database for future reference.
Certification Card
Along with the decal, a certification card is provided.
