Is grading worth it? The maths, honestly

What a submission actually costs once you include postage and insurance, the break-even most cards never reach, and the four cases where grading genuinely pays.

5 July 2026 · 7 minute read

Grading is sold as a way to make a card worth more. It is really a way to make a card easier to sell — and those are only the same thing above a certain value. Below it, you are paying to put a £20 card in a £30 box.

Count the whole cost

The submission fee is the number people quote, and it is rarely the number they pay. A realistic total is the fee, plus tracked insured postage there, plus return postage, plus the card savers, plus — if you are shipping outside the UK — the possibility of customs on the way back.

Run that total, then ask the only question that matters: what does this card sell for raw, and what does it sell for in the grade it is realistically going to get?

"Realistically going to get" is doing the work

Nearly everyone overestimates. The gap between a 9 and a 10 is often three or four times the value, and the things that separate them — centring inside a couple of percent, no print line anywhere on the surface, four genuinely sharp corners — are things a pack-fresh card fails all the time.

If you have never had a card graded, assume your first submission comes back a 9. If the maths only works at a 10, the maths does not work.

Where grading does pay

  • Vintage. A 1999 holo in a slab sells to a completely different buyer than the same card raw, because the slab settles the authenticity question before the price question.
  • Genuinely gem-mint modern chase cards, straight from a sealed pull, never handled.
  • Cards you are keeping. If it is going on a shelf for ten years, the holder is protection you were going to buy anyway.
  • Anything where authenticity is genuinely in doubt. A slab is the cheapest way to answer that.

Where it does not

Bulk modern rares, anything already showing edge wear, and — this one surprises people — most sealed-era reprints. If a card is being printed again next year, the grade protects nothing.

The UK shortcut

ACE grade in the UK, which removes the international postage and the customs risk in one go. For cards in the £30–£300 band, that difference is often the entire reason the maths works. We take submissions over the counter if you want to talk one through first — and we will tell you when the answer is "do not bother", because a customer who did not waste £40 comes back.
