Cardboard Journal's Take
MNT Grading
A stable Canadian hockey specialist — dependable within that niche, largely invisible outside it.
What Sets Them Apart
Canadian, founded 2016 in Brampton, Ontario, and carrying more verification infrastructure than most graders its size — a public cert lookup and a population report. Pricing is by turnaround only, with no declared-value tiers, so a CAD 10 card and a CAD 10,000 card cost the same to grade.

Marketplace Acceptance
Certificate lookup:Verify a cert →
eBay
Listed in eBay's professional grader filter, so MNT slabs are searchable, but MNT is not covered by the Authenticity Guarantee and carries no eBay buyer protection.
Auction houses
Not standard inventory at Goldin, Heritage or PWCC.
Card shops and general resale
Established recognition in Canadian hockey circles, supported by a public verification lookup and population report — more transparency infrastructure than most graders its size.
Acceptance is regional and category-specific: real inside Canadian hockey, thin in the wider US market.
Pricing
Priced by turnaround alone — there are no declared-value tiers, so a CAD 10 card and a CAD 10,000 card pay the same to grade. That is unusually favourable at the top end and the main reason to look here. The cost returns through insurance, which is extra above CAD 100 of declared value. Speed is where the money goes: CAD 60 for two days against CAD 19 for the slowest, with volume breaks at 10 and 20 cards.
The Slab
A conventional clear holder, unremarkable in build.
Example slab shown for reference — not a card I personally own.
The Label
SubgradesFour, on the label
A gold flip carrying four printed subgrades next to the green MNT mark — the Beckett template again, at a fraction of Beckett's standing.
Grader Use Cases
- Personal Collection
- Protection & Preservation
- Authentication
- Insurance
Personal collections, protection and authentication, strongest for Canadian hockey. Optional declared-value insurance above CAD 100.
Known Concerns
Recognition is concentrated in Canadian hockey and limited in the US. The population is small enough that there is little comparable sales data establishing what an MNT grade is worth on the open market. Reasonable inside its niche; for anything aimed at the broader US market the slab does little work.

History
MNT Grading has operated from Canada since 2016, making it one of the more established of the smaller independents.
Like KSA it found its market in hockey, and it is known for detailed labelling on hockey rookie cards — the kind of specificity a specialist audience values and a generalist grader tends not to bother with.
Its following is modest but stable, and concentrated in the Canadian market.
