PSA, CGC, SGC, and Beckett still dominate most grading conversations, but two newer names have built real followings around a very different pitch: AI-assisted grading.
Ace Grading, founded in the UK in 2021 by content creator Randolph, specializes in Pokemon and sports card grading with a UK-first distribution model. TAG Grading, based in the US, pairs computer vision and machine learning with a human verification pass and a detailed digital report on every slab.
Both companies had genuinely rough stretches in 2026, a security breach for one and a capacity crisis for the other, and both are still working to build the kind of secondary-market recognition PSA has had for decades.
Here's how the two actually compare on technology, pricing, and reliability.
Ace Grading's pitch centers on modern, consistent, and transparent grading, with free subgrades on every card and published centering thresholds that give collectors a clear standard to check submissions against. TAG Grading leans harder into the technology itself, using computer vision and machine learning for a first-pass review before a human grader confirms the final call.
Both approaches aim at the same core complaint collectors have about traditional grading: inconsistency between different human graders reviewing similar cards. Ace solves it through transparency and published standards; TAG solves it by putting a machine in the loop before any human touches the final grade.
Ace runs tiers from Basic at £18 per card, with a 20-card minimum and roughly 60 working-day turnaround, up to a Luxury tier at £120 with a two-day turnaround. An optional Ace Label add-on, priced at £3, extends the card's artwork onto the grading label itself rather than using a standard plain label.
Ace's core appeal for UK collectors is staying entirely inside the UK market, avoiding customs delays and transatlantic shipping that submitting to a US-based grader would require. That advantage does not carry over the same way for Canadian collectors, who face their own cross-border shipping either way.
Every TAG slab links to a DIG report, accessible through an NFC chip or QR code, breaking the card down across corners, edges, centering, surface, and dimensions, plus a Card Vision viewer that zooms into the actual card images up to 800x magnification. Alongside a familiar 1-to-10 grade, TAG assigns a granular TAG Score on a 1,000-point scale and labels specific flaws as DINGS, its own term for defects behind a given grade.
That level of detail goes further than a typical pop report, giving a buyer a genuine look at why a card landed at its specific score rather than guessing from the grade number alone.
TAG's pricing shifted through 2026: the original Basic tier ran $22 per card before a spring pause, and the lineup was rebuilt around a $29.95 Value tier once submissions reopened, with a newer Value Tier requiring a 10-card minimum opening in October 2026. Ace's £18 to £120 range converts to a wider CAD spread depending on tier, and shipping internationally to the UK adds cost and time that a US-based grader does not for most Canadian collectors.
For a Canadian collector specifically, TAG's US location generally means simpler, cheaper cross-border shipping than sending cards to the UK, even before comparing the per-card pricing itself. Group submissions in a resealable team bag before they go into any outer mailer, regardless of which grader you choose.
Ace suffered a break-in in 2024 that cost it some reputation, and 2026 brought steep price hikes on top of that history. TAG's 2026 was defined by a backlog crisis: Basic and Standard tiers paused May 1, Express paused May 28, after volume hit roughly 420 percent of monthly processing capacity, with the backlog falling 76 percent by late August before all five tiers reopened September 30 with the backlog down about 96 percent from its peak.
Neither setback is disqualifying on its own, but both are worth knowing before you ship cards to either company. A grader recovering from a real operational crisis deserves a closer look at current turnaround estimates rather than trusting the marketing copy at face value.
Ace carries a strong Trustpilot rating of 4.8 across more than 1,300 reviews, a genuinely solid reputation signal for a company this size. TAG posted roughly 40 percent year-over-year growth as of May 2026, real evidence collectors are choosing it deliberately rather than just testing it out of curiosity.
Both companies are still younger than PSA's decades of market history, so population reports and resale recognition for either company's slabs remain less established than the big four graders. That gap matters most if you plan to resell rather than hold.
TAG's US location, detailed DIG report, and faster-recovering pricing tiers make it the more practical option for most Canadian collectors shipping cards for AI-assisted grading today. Ace remains the stronger pick specifically for UK-based collectors who want to avoid transatlantic shipping entirely, which is less of an advantage once you are already shipping cross-border from Canada either way.
Whichever grader you pick, prep matters just as much as the company you choose. A card should go into a sleeve before it ever touches a submission envelope, and EVORETRO's Premium Card Sleeves are a simple first step for any batch headed out the door.
