What Are Roblox Item Values and How Are They Calculated?

If you've traded in Murder Mystery 2 or any Roblox economy game, you've seen items described by their "value." But values aren't set by the game — they're set by the community. Here's how they actually work.

Value is a market price

An item's value is a community estimate of what it's worth in a trade, usually measured against a common item (in MM2, the "seer"). It reflects what people are actually willing to give up for it — not an official price.

What moves values

• Supply — items no longer obtainable get scarcer and climb.
• Demand — popular, good-looking items hold and grow value.
• Rarity tier — higher tiers start from a higher base.
• Trends — hype from updates or creators can spike specific items.

Using values when you trade

Compare the total value of each side to judge whether a trade is a win, fair, or a loss — and never trade blind. Check a daily-updated list rather than old numbers: see the MM2 Value Checker for live values, or browse the store to buy directly.
