Security & Authentication
Protection designed into every slab
IGA slabs combine multiple security and verification elements, including tamper-evident design, NFC authentication, and verifiable digital certification, helping collectors, dealers, and hobbyists confirm the identity of each item and its recorded data.
Three Layers of Authentication
Tamper-Evident Design
IGA slabs are designed to show visible signs if opened or tampered with. The slab construction and Sonic Seal help protect the item and preserve its connection to the original certificate.
NFC Authentication
Each IGA slab includes NFC linked to the item’s digital certificate page. By tapping the slab with an NFC-enabled phone, users can access the certificate data and verify its connection to the item.
Public Verification
Every certificate number can be searched on igaverify.com, allowing users to match the slab, grade, description, and registered images against the official item record.
IGA Slab Types
Slab formats designed for different sizes of coins, medals, tokens, and special issues, while supporting documentation and digital verification.
Grande Slab
For larger medals, tokens, and special issues from 41mm to 65mm.
Larger format · Reinforced edges · NFC embedded
Multi-Item Slab
Configured for related sets, paired issues, year runs, or items intended to be displayed together upon request.
Custom configuration · Multiple chambers · Single NFC · Custom Label
All IGA slabs are designed to support preservation, presentation, and digital verification. Specifications may vary depending on item type, size, and selected service requirements.
Label Variants
Every IGA slab carries a printed label containing the item’s core data, certificate number, and grade. Special label types may be added when eligibility requirements are met.
Standard Label
The core label applied to every certified item, including item description, grade, certificate number, and IGA branding.
First Releases
Used for eligible items submitted within a defined period from the date of issue, according to approved criteria.
Pedigree Label

Signed Labels
A special label option for selected items or issues associated with approved signatures, where eligible.
Event Labels
Special commemorative labels for shows, events, institutional issues, or occasions connected to the collectibles market.
Special Designations
Includes technical designations such as Proof-Like (PL), Deep Cameo (DCAM), Plus Grade (+), and Star (★), applied only when the relevant criteria are met.
How to Spot a Suspicious Slab
Do not rely on the slab’s appearance alone. Proper verification should combine slab inspection, NFC reading, and matching the data and images on the certificate page.
Authentic Slab Indicators
- NFC responds when tapped with an NFC-enabled phone.
- Sonic Seal is visible along the slab edge.
- Label printing is sharp and consistent, with readable Microtext where present.
- Certificate number matches the verification result on igaverify.com.
- Images on the Verify page match the physical item.
Warning Signs
- No NFC response.
- Visible opening marks, cracks, glue, or repair on the slab.
- Blurry or inconsistent label printing.
- Certificate number returns Not Found on verification.
- Clear mismatch between the physical item and registered images, or between slab data and the Verify page.
When in doubt, use the Verify page first. Verification is available for any IGA certificate.
Slab Generations
As IGA slab designs evolve, each generation is documented to help identify original slab features and review earlier versions when needed.
Gen 1
Generation 1 — 2026 onwards
The current IGA slab design, combining a clear slab, Sonic Seal, NFC, and tamper-evident construction designed to show visible signs of opening or tampering.
Report a Suspicious Slab
If you encounter an IGA slab that does not match the Verify page, or one that shows signs of opening or tampering, please submit a report so the case can be reviewed. You may include the certificate number, clear front and back images of the slab, and close-up images of the label and slab edges.
You may also report without sharing personal details if preferred.
Verify with confidence
Every IGA-certified item should be connected to clear data, registered images, and a slab that can be inspected and verified.
