CERTIFICATE PROVENANCE

Deep Research record

Private working notes stay inside Operations. Publication requires a live Criterion Journal entry, which is linked from the certification record with the reviewed summary, ownership record, source list, and limitations.

HOLDER SECURITY

A new randomized code replaces any prior code. The complete code is displayed only once and must be applied to the assigned holder.

HOLDER SECURITY

Program Cryptographic NFC

Criterion uses NTAG 424 DNA Secure Dynamic Messaging. AES keys and raw tag UIDs must remain inside the approved key service and secure programming tool. Operations stores only the public tag ID, keyed UID-binding digest, and programming-receipt digest.

Tap Location Privacy

The public verification flow may request approximate device location after a tap. Coordinates are recorded only when the person tapping explicitly accepts the location prompt; declining does not prevent NFC authentication.

CATALOG IDENTITY

Validate and assign GSID

GSID is licensed from Greysheet. Criterion stores only the identifier and validation time. Catalog metadata and pricing are not copied into the public record.

Enter the GSID shown by Greysheet, then validate it before assignment.

SECURE HOLDER PRODUCTION

Build Folded Front and Back Label

Finished folded size is fixed at 49.5 × 19.5 mm. The unfolded one-piece sheet is 49.5 × 39.0 mm and requires registered front/back printing. The NFC tag is sealed inside the fold.

TRUE-RATIO PROOF

Front and Back

Proof previews may contain placeholders. Production export remains blocked until every readiness check passes.

CERTIFICATE IMAGING

Criterion Imaging Studio

Originals remain private and unchanged. Coin derivatives are auto-framed as transparent coin-only cutouts. Choose the correctly lit side as the pair reference; the other side is exposure-matched without changing white balance or color designation evidence. Any crop, orientation, or lighting flag must be reviewed before release.

REQUIRED FIRST

Add Obverse and Reverse Together

Select both original files before upload. Auto-frame removes the photography surface, preserves only the coin, honors the selected quarter-turn, and matches the non-reference side to the correctly lit reference. Confirm the visual top because design orientation cannot be safely inferred from a circular outline alone.

AFTER THE COIN PAIR

Add Optional or Holder Imaging

Add holder and crossover views when applicable.

Complete the obverse/reverse pair first.

Coin PairRequired: upload obverse and reverse
Criterion HolderOptional until the Criterion holder is photographed
Crossover SourceNot applicable to a standard certification

Upload the obverse and reverse to begin. Optional image products are omitted unless supplied.

PUBLISH CERTIFICATION

Make Certification Live

This publishes the record to the public verification registry. Coin imaging, A/B confirmation, label and slab completion, NFC activation, post-slab images, and explicit public-record verification must all be complete.
