PSA grading remains the single most consequential decision an Australian collector makes about any individual card. A clean PSA 10 routinely sells for 2–5x a comparable raw card. A PSA 8 on a card the seller hoped would 10 can sell for less than the raw equivalent. Here's how we think about the maths in 2025.
The current cost stack from Australia
- PSA Value tier (cards ≤ $499 declared): US$25 per card
- PSA Regular tier (cards ≤ $1,499 declared): US$75 per card
- Two-way international postage with insurance: AU$80–$150 per shipment
- FX + payment fees: 2–4% on top
- Turnaround at the Value tier in 2025: typically 30–55 business days
For a single Value-tier card, you're looking at ~AU$60–$80 all-in. The maths only works if the grading premium clears that cost.
When grading is obviously worth it
- High-confidence 10 candidates on cards with strong PSA 10 markets. Modern alt arts, SIRs, and chase pulls in clean condition. The premium for a 10 vs a 9 is typically large enough to clear the grading cost twice over.
- Vintage holos in genuinely strong condition. A clean Base Set holo that grades 8+ usually clears the cost. Below 8 is borderline.
- Bulk submissions of mid-value modern cards. If you can submit 20+ cards at once, the per-card postage cost becomes negligible.
When it's not worth it
- Cards where the PSA 10 market price is under ~$80. The premium can't clear the cost.
- Cards with visible centring issues, surface scratches or whitening on the corners. Don't gamble — PSA is brutal on centring.
- Heavily played cards. Anything that grades 6 or below typically sells for less than raw NM.
The Australian alternative: grading locally
Several Australian grading services have launched in the past two years. Turnaround is faster (often 7–14 days) and there's no international postage. The trade-off is that PSA-graded cards still command a meaningful resale premium over locally-graded equivalents in the AU market — typically 15–25%. For cards you intend to hold long-term and eventually resell, PSA usually still wins despite the wait.
How we factor grading into ZimCollects offers
Already-graded cards get an offer based on the grade and the live AU market for that grade. Raw cards get offered against raw NM market — we don't pre-grade or speculate on what a card "might" be in a slab. If you want to crack the slab and re-grade, that's your call to make.
