Why pre-grade your cards
A grading fee is gone the moment the card is in the mail. Pre-grading is how you decide whether that fee is worth it.
A slab does not create condition. It records it, then charges you for the record. Pre-grading is the look you take before that charge.
What you are actually buying
Grading companies charge a fee, and often shipping and insurance, whether the card comes back a 10 or a 6. The card is also gone for weeks. If you already know it has a crease, a soft corner, or centering a grader will notice, you paid to be told something a lamp and a loupe could have told you at the kitchen table.
Pre-grading asks four questions:
- Is the centering inside the window you are hoping for?
- Are the corners sharp, or just sharp in a sleeve?
- Is there edge whitening you stopped seeing because you like the card?
- Is the surface clean under a light, not just under a ceiling bulb?
Where the StockOasis tool fits
The pre-grade app at the hub is that pass, with a second set of eyes. Founding Member includes 4 cards a month, Premium includes 8, Premium+ includes 16, and Vendor is unlimited. A card counts as one pre-grade, front and back together, and only successful scans count.
It will not promise a grade. No honest tool can. Companies change populations, and two graders can disagree on a surface line. What it can do is stop the obvious misses: the card you love that is not the card a grader will love.
A simple rule
If the grading fee is a large share of the card's raw value, be picky. If you are grading it to keep, because you want it in a slab on your shelf, the math is different and that is fine. Say which one you are doing before you print the label.
