SECURITY & AUTHENTICATION
Trust Built Into Every Slab
How IGA holders combine tamper-evident design, NFC authentication, and verifiable certification to protect your collection's value.
Three Layers of Authentication
Tamper-Evident Design
IGA holders are sonically sealed with anti-tamper construction. Any attempt to open the holder leaves immediately visible damage.
NFC Chip Authentication
Every IGA slab carries an embedded NFC chip linked to its certificate. Tap with any modern phone to verify instantly.
Public Registry Lookup
Every certificate number is searchable on igaverify.com. Match the holder, grade, and images against the official record.
IGA Holder Types
Three holder configurations to fit every collectible — from miniature tokens to oversized medals.
Oversized Holder
Large medals and tokens from 41mm to 65mm
Same optically clear polymer · Reinforced edges · NFC chip embedded
Multi-Item Holder
Configured for paired sets, year runs, or related groupings on request
Custom configuration · Up to four chambers · Single NFC chip · Custom label
All IGA holders are archivally rated and include NFC authentication. Custom configurations available for institutional submissions.
Label Variants
Every IGA holder carries a printed label. Special qualifying labels are applied automatically based on eligibility.
Standard Label
Coin description, grade, certification number, and IGA branding. Applied to every certified item.
First Releases
Coins submitted within the first 30 days of issue. Adds the 'First Releases' designation to the label.
Pedigree Label
Records the documented provenance — previous collection, auction, or institutional ownership. Available with supporting documentation.
Signed Labels
Labels personally signed by recognized numismatic experts or historical figures, where eligible.
Event Labels
Special commemorative labels for major numismatic shows, conventions, or institutional anniversaries.
Special Designations
Quality designations like Proof-Like (PL), Deep Cameo (DCAM), Plus grade (+), and Star (★) — applied automatically when criteria are met.
Spotting a Counterfeit Holder
An IGA holder cannot be silently faked. Here's exactly what to check.
Authentic IGA Holders
- NFC chip responds when tapped with a phone
- Sonic seal visible at the holder's edge
- Label printing is sharp and microtext readable
- Certificate number matches the verification result on igaverify.com
- Coin images on Verify match the physical coin
Warning Signs
- No NFC response from the holder
- Visible seam, glue, or repair on the holder
- Label printing is fuzzy or inconsistent
- Certificate number returns 'Not Found' on Verify
- Coin appearance differs from the verification images
When in doubt, always verify. The Verify page is free and works for any IGA certificate.
