Ripped & Wooden Certificate of Authenticity: Storage Hunters
Updated 2026-09-09 · Last verified 2026-09-09 · Roblox Storage Hunters: Open World
What do you do with a Ripped Certificate of Authenticity? Take it to the Authenticator, pick a head, back or wrist accessory, and spend the certificate: the accessory gains one permanent random bonus stat and the certificate is consumed. Nothing is broken and nothing needs repairing, because "Ripped" is simply the name of the Rare certificate tier, and it works at the Authenticator exactly like the Epic Wooden Certificate of Authenticity.
That is what every Certificate of Authenticity in Storage Hunters: Open World is for. The bonus can be extra Walkspeed, Tip Chance or Bid Zone Width, among others, and authenticating costs nothing beyond the certificate itself: no Robux, no Diamonds. Both Ripped and Wooden certificates drop from auction containers in every area of the map.
Ripped Certificate of Authenticity: what it is and what to do with it
"Ripped" is a rarity label, not a damage state. There is no repair, sewing or restoration step documented anywhere on the Certificates or Authenticator pages, and a Ripped certificate is never rejected by the Authenticator. If one is sitting in your inventory, the only thing to do with it is spend it.
The single difference from a Wooden certificate is the range it rolls. Ripped draws from the same stat pool, but on every shared stat it rolls a strictly lower band:
| Stat | Ripped (Rare) | Wooden (Epic) |
|---|---|---|
| Bid Recovery | 3.8% – 13% | 5% – 25% |
| Bid Zone Width | 11% – 38% | 15% – 75% |
| Tip Chance | 2.3% – 7.5% | 3% – 15% |
| Walkspeed | 7.5% – 25% | 10% – 50% |
| Energy Drink Time | 7% – 25% | 10% – 50% |
So a Ripped certificate is worth roughly half a Wooden one on the stats above, and that is the whole penalty. It is still a free permanent buff on an accessory that otherwise has none.
One thing to weigh before spending it. Any later authentication replaces the previous bonus, so using a Ripped certificate now and a Wooden one later means the Ripped roll is overwritten. Whether to hold the accessory and wait for a Wooden certificate is a judgment call, not a documented rule. If the accessory is one you are still levelling towards, or you have spare certificates, there is no reason to sit on a Ripped one: certificate sale values are listed as "Varies" in the item data, so no fixed sale price is documented for either tier.
The serial number query comes up often, but neither the Certificates nor the Authenticator page on Fandom documents a serial-number system for certificates. Treat anything you read about serial numbers as community-reported, unconfirmed.
Certificate types
Three certificate types are documented.
| Certificate | Rarity | Where it comes from | What it does |
|---|---|---|---|
| Ripped Certificate of Authenticity | Rare | Auction containers, all locations | Rolls a basic or exclusive stat with a narrower range |
| Wooden Certificate of Authenticity | Epic | Auction containers, all locations | Rolls a basic or exclusive stat with the full range |
| Certificate Of Alienticity | Mythical | Alien Market roll, 25 Alien Coins (3.4% chance per roll) | Stamps one of six slot-locked Alien Authentications instead of a normal stat |
Wooden and Certificate Of Alienticity roll identical ranges on every basic stat they share. The Alienticity advantage is access to the Alien Authentications, which a Wooden certificate can never roll. The Alienticity was tied to the Alien Invasion event (August 16–30, 2026) and was also handed out as a reward for several Alien Invasion event quests. The event has ended, so it is no longer obtainable.
Bonus stat ranges
These ranges are for an unmutated certificate. "Not yet confirmed" means nobody has recorded that roll yet, not that the stat is unavailable. A dash means the stat cannot come from that certificate type at all.
Basic stats (any accessory slot)
| Stat | Ripped | Wooden | Certificate Of Alienticity |
|---|---|---|---|
| Bid Recovery | 3.8% – 13% | 5% – 25% | 5% – 25% |
| Bid Arrow Speed | 15% – 30% (unconfirmed) | 12% – 60% | 12% – 60% |
| Bid Zone Width | 11% – 38% | 15% – 75% | 30% – 75% |
| Tip Chance | 2.3% – 7.5% | 3% – 15% | 3% – 15% |
| NPC Offers Bonus | 2.3% – 7.5% | 3% – 15% | 3% – 15% |
| Walkspeed | 7.5% – 25% | 10% – 50% | 10% – 50% |
| Energy Drink Time | 7% – 25% | 10% – 50% | 10% – 50% |
Exclusive stats (slot-restricted, Ripped and Wooden only)
| Stat | Slot | Ripped | Wooden | Effect |
|---|---|---|---|---|
| Sunny | Head | Not yet confirmed | 10% – 100% | Increases luck during the day |
| Nocturnal | Head | Not yet confirmed | 10% – 100% | Increases luck during the night |
| Overcharged | Head | Not yet confirmed | 5% – 20% | Energy Drinks grant more luck while worn |
| Raindrop | Back | 8% – 50% | 10% – 100% | Increases luck while it rains |
| Focused | Back | Not documented yet | Not documented yet | Boosts the accessory's strongest original buff |
| Timekeeper | Wrist | 4% – 20% | 5% – 40% | Reduces the free Time Capsule roll cycle while worn |
| Connected | Wrist | Not yet confirmed | 2% – 12% | Adds a random extra Luck bonus per friend on the server |
Raindrop and Timekeeper are the two exclusive stats a Ripped certificate is confirmed to roll. The other five are only recorded from Wooden certificates so far, which is a gap in the records rather than a confirmed restriction.
Alien Authentications (Certificate Of Alienticity only)
| Authentication | Slot | Range | Effect |
|---|---|---|---|
| Haggler | Back | 5% – 10% | Quick Sell shop pays a higher percent while worn |
| Anti-Gravity Field | Back | 5% – 25% | Increases the equipped vehicle's weight capacity |
| Safecracker | Head | Not documented yet | Diamond safes and vaults pay out more Diamonds |
| Grade Re-Roll | Head | 10% – 25% | Chance for a free second roll when grading lands Replica or 1 Star |
| Exhibitor | Wrist | Not documented yet | Items displayed in the Museum grant a boosted bonus |
| Rush | Wrist | 10% – 25% | Chance for an auction to begin immediately when its door opens |
Those six Alien Authentications are confirmed as the complete list.
What authenticating an item means
"Authenticating" an accessory means spending a certificate at the Authenticator to attach a permanent bonus stat to it. The stat type is rolled randomly from the pools above. The certificate's quality only shifts how strong the number is likely to be, not which stat you get.
The bonus is attached to the accessory itself. The Authenticator is only documented as working on accessories, not on regular auction items or vehicles.
How to use a Certificate of Authenticity
- Go to the Authenticator. It is a service area, and the Club spot sits right next to it.
- Select the accessory you want to buff.
- Select one certificate (Ripped, Wooden or Alienticity) from your inventory.
- Confirm. The certificate is consumed and the accessory receives its bonus.
Re-rolling right after a roll
Immediately after any authentication roll, two paid options appear. Each costs a flat 199 Robux and does not use another certificate:
| Option | Cost | Result |
|---|---|---|
| Reroll | 199 Robux | Rerolls the stat itself; can land on a completely different stat |
| Reroll Number | 199 Robux | Keeps the same stat and rerolls only its percentage |
These two options only exist right after a roll. If you come back later and want a new bonus, you have to authenticate again with a fresh certificate.
Re-authenticating an accessory
An accessory that already has a bonus can be authenticated again with another certificate. The new roll replaces the old bonus. It never stacks a second stat, and the previous result cannot be recovered.
Certificate quality: mutation and grade
Certificates are items, so they can carry a mutation and a grade like anything else you pull from an auction. Both change the strength distribution of the roll: better mutations and grades push the result toward the top of the stat's range. Fandom hosts a distribution chart for this, but the exact per-mutation and per-grade shifts are not documented as numbers yet.
One confirmed example: a Secret-mutated Wooden certificate shifted the Overcharged floor from 5% up to 9%, while the maximum stayed at 20%. In that case the mutation raised the floor of the roll and left the ceiling unchanged.
This is also the one way a Ripped certificate improves: a mutated, well-graded Ripped certificate rolls higher inside its own band than a plain one. It does not turn into a Wooden certificate, and the Ripped ceilings in the table above still apply.
Whether grading a certificate at the Grading Store before using it is worth the fee is not documented. The general rule from the source is simple: a higher-grade, better-mutated certificate gives a better expected roll on the same stat.
Where certificates drop and authentication chances
Certificates drop from auction containers in any area, and they are not tied to a specific location or auction pool. Business Bay was confirmed to drop certificates after a same-day hotfix. The exact drop chance per container is not documented yet, and certificate sale values are listed as "Varies" in the item data.
The chance of rolling each individual stat during authentication is also not documented. The only published odds are for the Certificate Of Alienticity itself: a 3.4% chance per 25-Alien-Coin Alien Market roll during the event.

Frequently asked questions
What do you do with a Ripped Certificate of Authenticity?
Take it to the Authenticator and use it on a head, back or wrist accessory: it grants one permanent random bonus stat and is consumed. Ripped is just the Rare tier, not a damaged item. It rolls the same stats as a Wooden certificate but in a strictly narrower band, for example Walkspeed capping at 25% instead of 50%.
Can you fix or repair a Ripped Certificate of Authenticity?
There is nothing to fix. Ripped is the name of the Rare certificate tier, not a damage state, and no repair, sewing or restoration mechanic is documented anywhere on the Certificates or Authenticator pages. A Ripped certificate works at the Authenticator exactly like a Wooden one; only the roll range is weaker.
What does the Certificate of Authenticity do in Storage Hunters?
It attaches one permanent random bonus stat to an accessory when you spend it at the Authenticator. Possible stats include Bid Recovery, Bid Zone Width, Tip Chance, NPC Offers Bonus, Walkspeed and Energy Drink Time, plus slot-restricted ones like Sunny, Raindrop or Timekeeper. Authenticating costs nothing beyond the certificate itself, no Robux and no Diamonds.
How to use Certificate of Authenticity in Storage Hunters?
Go to the Authenticator service area, select the accessory you want to buff, pick one certificate from your inventory and confirm. The certificate is consumed and the accessory receives its bonus.

What is the difference between the Ripped and Wooden Certificate of Authenticity?
Ripped is the Rare tier and Wooden is the Epic tier. They roll the same stats, but Ripped uses a strictly weaker range on every shared stat. Bid Recovery rolls 3.8%-13% on Ripped versus 5%-25% on Wooden, and Tip Chance caps at 7.5% versus 15%. Both drop from auction containers in every area of the map.
Is a Ripped Certificate of Authenticity worth selling?
Certificate sale values are listed as "Varies" in the item data, so no fixed price is documented for either tier. What a certificate is reliably worth is the roll itself: one permanent bonus stat on an accessory, for free, at the Authenticator.
