- Check identity. Read the set, number, language, printing and grade against the physical card.
- Check the date and source. A saved value is evidence from a previous lookup. Refresh while connected if needed.
- Keep unknowns visible. No price means no usable value for that selection. It does not mean the card is worth zero.
- Agree on a value. If you and the other trader choose an amount, label it as your agreed value. It is separate from market evidence.
- Pause if needed. Save the table or card and come back when you can verify it.
On the website calculator, an unpriced card makes totals partial and removes the trade verdict. Enter an agreed value or remove that card before comparing the sides.
