What this MM2 trade checker is for
Valuro is a free MM2 trade checker for Murder Mystery 2. You put your offer on one side, their offer on the other, and the tool adds the values so you can see whether the deal is a win, fair, or loss before you tap Accept in-game. It does not complete the trade, hold items, or talk to Roblox. It is a calculator you use next to the real trade window.
That split matters. A screenshot, a Discord message, or a voice chat promise is not the trade. Only the items sitting in the in-game window when both players accept will move. Use this checker to plan and to double-check the numbers; use the game itself to confirm the items.
For context, the official Murder Mystery 2 page on Roblox invites players to Collect and trade hundreds of knives!
— it does not publish any value list. Values here are community median estimates from public MM2 value lists (mm2calc.com, supremevalues.com) · Snapshot collected Nov 1, 2026. Every number is still editable.
Check both sides before you accept
A lot of bad MM2 trades happen because one side is described in chat and the other side is assumed. The checker forces both offers onto the same screen. Add what you are giving, then switch the target and add what they are giving. Stack duplicates by tapping the same item again. If a knife, gun, pet, or set is not in the catalog, add it as a custom item with a name and a value from the list you trust.
As you type, the totals update. Within 5% of the larger total is Fair. Getting more listed value is a Win. Giving more is a Loss. Those labels are arithmetic on the numbers you entered — not a promise that the items will be easy to trade on later. If a value looks wrong, edit it. Edited slots are marked so you can see which numbers came from you and which came from the catalog.
When you want a second opinion, share the trade link. Anyone who opens it sees the selected items, quantities, edited values and user notes. Unedited values use the current catalog. That is useful when a friend is asking “is this fair?” in a hurry. It is not a substitute for looking at the live trade window yourself.
- Open the value list you actually use and keep it next to this page.
- Add up to four different items on your side. Tap again to raise quantity.
- Add their side the same way. Fill empty slots instead of guessing.
- Type list values into any slot that does not match what you trust.
- Read the win / fair / loss result, then think about demand and whether you even want the items.
- In Roblox, confirm every slot matches this screen, then accept only if it still looks right.
Common MM2 trade scams and how to avoid them
Value checkers cannot stop a scam by themselves. They help you notice when an offer is lopsided on paper. The rest is habit: trade only in the official window, never share a password, and never treat a screenshot as proof.
Inflated values on one side
A common trick is to talk up a mid-tier item as if it were a high Godly or Ancient, then ask you to “add a little” so the deal “looks even.” If you accept the story instead of the numbers, you overpay. Put both sides in this MM2 trade checker using the same list. If their item only looks good after they pick a much higher number than every public list, that is the scam — not a bargain.
Fake rare-item screenshots
Screenshots are easy to crop, reuse, or take from someone else’s inventory. A chroma knife in a photo does not mean that knife is in the trade. Ignore gallery images and party chat previews. The only items that count are the ones in the trade window at accept time. If they stall, swap a slot at the last second, or ask you to accept first “because the screenshot is real,” decline.
Last-second slot swaps
Some players fill a fair trade, wait until you are about to accept, then swap a high-value item for a cheap lookalike. Pause. Scroll both sides again. If anything changed, cancel and rebuild the checker. A fair result on this page means nothing if the live window no longer matches it.
Trust trades and fake middlemen
Anyone who asks you to drop items, join a “checking” game, or hand over your account so they can “verify values” is not helping. Valuro never needs your password, Roblox cookie, or inventory access. There is no official MM2 middleman inside this site. If a stranger claims they work for Valuro, Roblox, or the game’s creators, they do not.
Offers that look too good
A huge Win on paper is often a low-demand item you will not be able to trade on, or an item that is about to be swapped out of the window. If the deal only works if you rush, it is not a deal. Check demand and recent list movement on How MM2 values work, then confirm the live slots.
- Trade only through the in-game trade window. Items promised outside it cannot be recovered.
- Before the final accept, read every slot on both sides again.
- Do not share passwords, backup codes, or session cookies for a “value check.”
- Do not accept because a screenshot, a friend-of-a-friend, or a voice chat said the items were rare.
- If the numbers only work on one obscure list, run the same trade on a second list before you agree.
MM2 rarity terms, without made-up prices
Murder Mystery 2 items are grouped by rarity so players can filter a catalog. Rarity is not the same thing as value. A Godly can be easier to trade than an Ancient with weak demand. Valuro uses the rarity labels that appear on public community lists, then lets you filter the picker by them. The live catalog is what the weekly refresh last stored; example names and values are used when that catalog is unavailable.
Godly is the label most traders mean when they say “a godly.” These are the everyday high-tier knives and guns people use as units when they describe a deal.
Ancient sits above typical Godlies on most lists. Players treat Ancients as destination pieces. That still does not tell you today’s number — open the item in the checker and read the estimate, then edit it if your list disagrees.
Chroma marks recolored or chroma variants. Chromas are often discussed as their own market. A chroma and a non-chroma with similar names are different items; add the one that is actually in the window.
Legendary, Rare, Uncommon, and Common are the lower rungs. They still belong in a trade when someone is adding small items to balance a larger one. Do not ignore them because the headline item is a Godly — small adds are how many unfair trades get hidden.
Vintage and Unique flag older or unusual pieces that lists track separately. Set is a bundled set rather than a single weapon. Pet is a pet. Other and Custom cover anything the sources did not map, or an item you typed in yourself.
None of those words is a price. Two Godlies can be far apart. Two Chromas can move in opposite directions in the same week. If you need the idea behind the number — points, demand, stability, why lists disagree — use the longer guide: How MM2 values work. This page will not invent a value table. Each item shows the community estimate currently stored for it.
How to read Win, Fair, and Loss
The checker multiplies each item’s value by its quantity, sums your side, sums their side, and compares the two totals. If the difference is within 5% of the larger side, the result is Fair. If you receive more than that margin, it is a Win. If you give more, it is a Loss. Empty or one-sided trades do not get a verdict until both offers have at least one item.
Values are points used by community lists, not Robux and not real money. Valuro does not convert points into a currency. A Win can still be a bad trade if you cannot move the items you just received. A Loss can still be a trade you want if you are collecting a specific piece. The math is there so you see the gap; you still decide whether the gap is acceptable.
FAQ
Is a Win always a good trade?
No. An item with low demand can be hard to trade on, even at a high value. There is no official MM2 value list, so check demand and recent changes, and confirm the items in the in-game trade window before you accept. Read how MM2 values work.
How often does this MM2 trade checker update its values?
Community median estimates are compiled on a weekly schedule from public MM2 value lists (mm2calc.com and supremevalues.com) · Snapshot collected Nov 1, 2026. Refreshing the catalog does not lock the numbers. Edit any slot whenever your trusted list has moved, or when two lists disagree and you want to test the low and high ends of the range.
Which item types are supported?
The picker can filter Ancient, Godly, Chroma, Legendary, Rare, Uncommon, Common, Vintage, Unique, Set, Pet, Custom, and Other. Those labels match the rarity map used by the values pipeline. If an item is missing from the weekly catalog, add a custom row. Custom items stay on this device and in share links you create; they are not written back into the public catalog.
Does a Fair result mean I should accept?
Fair only means the difference is within 5% of the larger total. It does not check demand, stability, or whether the items on this page match the in-game window. If you care more about a specific knife than about the point total, ignore the label and trade for the item. If you care about listed value, treat Fair as “close on paper,” then do the live-window check.
Can I use a different value list than Valuro’s catalog?
Yes. That is the point of editable values. Keep your list open, type its numbers into the slots, and read the result. The catalog is a starting point from available public sources, not a rule that you have to follow.
Does this tool need my Roblox account?
No. There is no login, no inventory import, and no way for the page to see what you own. You pick items by name. If someone asks you to sign in “so Valuro can check the trade,” that is a scam.
Why do other sites show different numbers?
Each list is kept by different people who watch different trades and update on different days. Seeing a gap between sites is normal. Use the range: run the trade at the low estimate and the high estimate. If it only looks fair on the most optimistic number, it is probably not fair. The about page explains demand and stability in more detail.
Is Valuro affiliated with Roblox or MM2?
No. Valuro is an independent fan tool. It is not affiliated with Roblox or the game’s creators. The official game page still does not publish item values, which is why community lists exist and why every value here stays editable.
