storage hunters open world grading: Tier Guide & Tips

In storage hunters open world grading, an item receives a rolled grade that changes its final value. The available results range from Replica through 3 Star, with each tier applying a different value multiplier. Grading is handled at the Grading Store inside the Shopping Mall, a central service area that also includes washing, repairing, lockpicking, quick selling, and other progression services.

A grade affects value rather than replacing the item's underlying identity. This makes grading especially important when deciding whether an item should be sold immediately, improved through another service, or kept for a better opportunity. Higher grades are more valuable, but the roll is not guaranteed, so players should consider the item's base value and the cost of additional attempts.

The Shopping Mall page also notes that grading time depends on item rarity. Common items grade quickly, while Mythical items take noticeably longer. Plan around that timing when processing several valuable finds instead of expecting every item to complete at the same pace.

Standard grading uses four listed outcomes: Replica, 1 Star, 2 Star, and 3 Star. The published standard odds are 22%, 38%, 35%, and 5%, respectively. These figures show why 3-Star results are valuable: they have the largest multiplier but the lowest standard chance in the listed table.

The Lucky Grading Gamepass changes the listed distribution. Replica results become 0%, while 1-Star results are listed at 36%, 2-Star results at 54%, and 3-Star results at 10%. This does not guarantee a high-grade result, but it shifts the published odds away from the lowest outcome and toward the upper tiers.

The odds table is most useful as a planning tool. A player who grades many ordinary items may prefer to accept the first result and keep moving. A player processing an especially valuable find may see more reason to pursue a stronger result, particularly when Lucky Grading is available.

The game also includes a Grade Reroll% stat. When an item rolls Replica or 1 Star, this stat can provide a chance for a free reroll. The referenced example uses a 20% Grade Reroll stat, which would represent a 20% chance at a free reroll on a bad grade. This stat was associated with Jurassic Area accessories, and those accessories are no longer available after the event ended.

The Grading Store provides three listed slots. Slot 1 is free. Slot 2 requires 50 Diamonds and $10,000 Net Worth, while Slot 3 requires 150 Diamonds and $50,000 Net Worth. These requirements make additional slots a progression milestone rather than an immediate purchase for a new player.

More slots can improve workflow because several items can be placed into the grading process. However, added capacity is most useful when the player has enough finds to keep each slot active. Unlocking a slot before maintaining a steady supply of items may provide less practical value than improving the rest of the selling route.

Follow this process to keep grading organized:

Grading is only one part of the Shopping Mall's item-processing loop. Washing removes the Dirty mutation and can increase value through Pure or Spotless results. Repairing restores damaged items with wrench tiers. Quick Sell provides a direct selling option, while the Museum offers display-based progression and leaderboard goals.

These systems serve different purposes. Grading changes the rolled value tier, while cleaning affects washing mutations and value. The Shopping Mall information specifically states that cleaning and the Time Capsule affect an item's value, not its stats. Repairing is instead about restoring damaged items so they can be handled appropriately.

The Repair Store sells Basic, Steel, Precision, and Master Wrenches. Their listed prices are $75, $750, $10,000, and $100,000, with repair limits ranging from items worth up to $500 to any value. If a graded item is damaged, account for repair requirements before treating its grade as the final stage of preparation.

The Museum also tracks Top 3-Star Grades among its community leaderboards. That makes high-tier grading relevant beyond ordinary cash value. If your goal includes Museum progress or leaderboard placement, keep suitable 3-Star results rather than automatically sending every high-grade item to Quick Sell.

A strong grading routine depends on consistent decisions rather than chasing every possible upgrade. Start by unlocking access to the basic process, then build enough Diamonds and Net Worth to expand your slots. Once your inventory contains more valuable finds, Lucky Grading becomes more relevant because its listed odds remove Replica results and increase the chance of upper-tier outcomes.

Use the following checklist when developing a grading routine in 2026:

Re-grading costs Robux on a four-tier scale, with the listed first two tiers costing 9 and 49 Robux. Because the source data does not provide the remaining tier values, do not assume a fixed cost for every item. Review the displayed price before confirming an additional attempt.

The Energy Cafe can also stock Luck-boosting drinks. The listed examples are Luck Drink 1, providing +50% Luck for 12 Diamonds or 35 Robux, and Luck Drink 2, providing +150% Luck for 25 Diamonds or 99 Robux. These drinks are separate from the grading table, so do not treat their Luck effect as a guaranteed grade outcome.
