300 Slab Displays, 6 Coin Shops, and the Millimeters Between NGC and PCGS

The Challenge

Six stores, six different counters. The chain had grown one acquisition at a time, and its slab merchandising showed it: business-card easels doing double duty, jewelry ring stands with slabs balanced across them, and a few generic "universal" holders that gripped nothing correctly. Graded coins — the highest-value inventory in the store — leaned at odd angles, slid when the counter got bumped, and photographed crooked in listing photos. Key-date coins sat loose on open counters within arm's reach of customers.

The buying team wanted one visual system across all six locations and a secure option for the coins that justify a case with a lock. But the requirement that shaped the whole project was fit. Graded coins live inside rigid holders from two main services, and the two are not interchangeable: an NGC slab runs about 82 × 58 × 8 mm, a PCGS slab about 85 × 56 × 8.5 mm. A slot cut loose enough to accept both grips neither — the slab tips, rattles, and reads as exactly the kind of afterthought the chain was trying to retire. Their previous "universal" holders had taught them that lesson at full price.

Our Approach

We built the project around three decisions: verify fit on real slabs before cutting anything, consolidate every counter job into three SKUs, and pack the order so six stores could be reset without a distribution center touching a single piece.

Fit verified on the chain's own slabs

Published slab dimensions are a starting point, not a production spec — holders vary by generation, and the edge profile matters as much as the outline. So the chain mailed us two slabs from their own inventory, one NGC and one PCGS. We measured both directly, cut sample slots to each profile with about 1 mm of clearance on length and width, and tested the motion that matters at a counter: insert, grip, remove, repeat. The slab has to seat with light pressure, hold its angle when the counter is bumped, and come out one-handed for a customer who asks to see the coin. The 3-SKU sample set went out in 5 days, and production started only after the chain approved the fit on their own slabs.

Three SKUs for every counter job

Instead of a different holder for every situation, the system runs on three pieces. The single-slab stand — 3 mm clear acrylic, a 12-degree backward lean so the coin face reads under counter light — handles the featured coin next to the register and doubles as a photo stand for online listings. The six-slot block displays sets and date runs, with felt-lined recesses and NGC and PCGS profile slots cut side by side in the same block, so a mixed set displays as one row with every slab seated correctly. And the lockable countertop case — 5 mm walls, cam lock, an angled interior tier — holds key-date coins where customers can study them but not pick them up. The format logic behind these choices is laid out in our coin display ideas guide; this chain's mix was 216 stands, 72 blocks, and 12 lockable cases — 36, 12, and 2 per store.

Packed by store, not by SKU

A 300-piece order for one address is a stack of cartons; a 300-piece order for six addresses is a logistics problem someone has to solve, and by default that someone is the buyer's back room. We packed the run as six store sets — each store's 50 pieces cartoned together and labeled by location — so the chain cross-docked the shipment straight to stores. No central repacking, no counting pieces out of SKU cartons, no store waiting on a partial kit. Every location had its full set the same week, and the chain reset all six counters over a single weekend.

The Results

All 300 pieces shipped from an 18-day production run after sample approval, passed 100% inspection against the approved samples, and reached six stores as complete, store-labeled sets.

The fit verification is the part of this project that repays reading. It cost the chain two slabs and a week of calendar, and it removed the single most common failure in slab merchandising: display stock that arrives and grips the inventory wrong. Every complaint the chain had about its old counters — leaning slabs, rattling holders, crooked listing photos — traced back to slots that were never cut against a real holder. Measuring the actual slab before production is a small discipline, and it is the entire difference between "acrylic display" and "display for this exact object."

The rollout also left the chain with an asset that does not sit on any counter: the drawings. Slot profiles, SKU geometry, and cutting files are retained under the chain's account, so the two new locations on their roadmap order their 50-piece store sets as a repeat run — no re-sampling, no re-measuring, same fit as the first six stores.

What This Means for Your Project

If your displays hold a standardized object — graded coin slabs, graded card slabs, capsules, bullion bars — the deciding question for any supplier is: will you cut the slot against the real thing? Published dimensions drift across holder generations, and a display that is off by a millimeter fails at retail in a way no spec sheet predicts. Mail one piece, get a sample slot cut and fit-tested, then commit to volume. The same discipline applies one product category over: our graded card display cases solve the identical slot-to-profile problem for PSA, BGS, and SGC card slabs, and we quote coin and card formats together for shops that handle both.

For multi-location buyers, the second lesson is to make packing part of the spec. Store-set packing costs a conversation at ordering time and saves a back room a full week at delivery time. A 50-piece MOQ per design means a single shop can run this exact playbook — one store set, three SKUs, slots cut to the slabs you actually stock — without committing to chain-scale volume.
