For years, getting a card graded to a recognised standard meant shipping it to the United States and waiting. That’s changing. Here’s how grading in the UK compares to sending your cards overseas.

The cost of going overseas

Sending cards to a US grader means international postage both ways, paying in dollars, potential customs charges, and the risk of a valuable parcel crossing the Atlantic twice. The grading fee is only part of the real cost.

The time

International shipping plus overseas queues can mean weeks — sometimes a couple of months — before a card comes home. Grading domestically removes the transit time entirely. CALIBRE’s standard turnaround is 72 hours from receipt, with a 24-hour priority option.

The approach

There are three broad approaches to grading: human graders assigning a grade by eye, AI models predicting a grade from photos, and physical measurement. CALIBRE measures the card — centering, corners, edges and surface — with sensors, so the same card produces the same grade every time, with a full report behind it. We break the categories down in our market comparison.

When does overseas still make sense?

If you specifically need a particular label for a particular market, that’s a valid reason to ship overseas. But for most UK collectors who want an accurate, verifiable grade without the cost, customs and wait, grading at home is simply more practical.

The bottom line

Grading in the UK means no customs, no currency conversion, no weeks in transit, and a card that never leaves the country. Start your order →

The UK card grading market today consists of three clearly distinct approaches. CALIBRE represents a fourth.

Three existing approaches

Before CALIBRE, UK collectors had three options for getting cards graded. Each represents a fundamentally different philosophy about what grading is.

Human inspection

The traditional approach, offered by PSA, Beckett, Ace Grading, MGC, and others. A trained human grader examines each card by eye, under standardised lighting, and assigns a grade based on their visual judgement. This has been the industry standard for decades.

The limitation is reproducibility. Human graders make different decisions on different days. Submitting the same card twice often produces different grades. Different graders within the same company disagree. The same card sent to two different companies almost always receives two different grades.

AI prediction

A newer generation of graders — REX in the UK, SSINT with operations across Asia and Europe, and others — use machine learning to estimate grades from photographs. The model is trained on a library of previously-graded cards and learns to predict what grade a human would likely assign to a new image.

This is faster and more consistent than human grading, but it is still a prediction. The model does not measure the card; it makes an educated guess based on what it has seen before. Cards that look unusual, that fall outside the training data, or that have rare defects can produce unreliable predictions.

Physical measurement — overseas only

Until CALIBRE, only one company in the world offered measurement grading: TAG, based in California. TAG uses photometric stereo and multi-spectral imaging — the same approach CALIBRE uses — to measure cards rather than judge them. TAG serves UK collectors through a forwarding agent. Cards are sent from the UK to the US office, on to California for processing, then back to the UK office, and finally to the collector.

The approximate end-to-end turnaround for TAG via the UK agent is eight weeks. Cards cross the Atlantic twice and spend significant time in international shipping.

The fourth approach

CALIBRE adds a fourth category to the UK market: domestic physical measurement. The same fundamental approach TAG uses in California, but operating in the UK, with domestic turnaround times, no international shipping, no customs, and flat transparent pricing.

What this means for collectors

The right grader for a given card depends on what the collector values. For established resale markets and cards where brand recognition drives premium value, PSA and BGS slabs still command the highest prices despite their long turnaround times. For fast, cheap grading of bulk cards, REX or SSINT offer good value.

CALIBRE is the right choice for collectors who value:

• Speed. 72 hours for a full grade, 48 hours for authentication.
• Determinism. Repeatable grades that do not change between submissions.
• Authentication confidence. Physical verification rather than AI prediction or human opinion.
• Domestic processing. Cards never leave the UK. No customs, no international shipping risk.
• Transparent pricing. £12 per card on standard grading. No upcharges based on card value, no holo/non-holo distinction.

CALIBRE does not compete with traditional human graders on price or with AI graders on speed. CALIBRE occupies the only position in the UK market that offers physical measurement — the approach used by TAG in the United States — but with domestic processing, faster turnaround, and flat transparent pricing.
