Slab Tags

Same identity.
New finish.

Three tiers, one skeleton: card metadata on the left, the grade in the centre, the four sub-grades on the right. The verso pairs the Excalibur crest with a QR code linking to the card's video examination. Every slab is itself a transparency device.

Design rules

One language,
two surfaces.

The same palette as the website. The same crest. The same restraint. What changes between tiers is the finish: every slab carries a finish tied to its grade, and the verso always anchors to the wordmark and a QR linking back to the examination.

01 — STRUCTURE

Three columns, always.

Card metadata · grade · sub-grades. A single skeleton, instantly readable from across a room.

02 — TIER FINISH

Finish by grade.

Black for the apex (Prismatic 10). Deep brown for Gem Mint 9. Cream for Mint 8 and below; slabs 1–6 share the same shell. The crest is the only constant.

03 — VERSO

Crest + QR.

The full Excalibur wordmark anchors the verso, paired with a QR code that opens the YouTube examination directly. The slab is itself a verification device. No app, no portal, no friction.

More tier variants and physical mockups arrive in phase 02 of the proposal.
