Memento Mori: Roblox's Rarest Surviving Gem Hat

Memento Mori is one of Roblox's oldest gems, down to 13 surviving copies from an original run of 26. Its full history, rarity math, and market data.

Memento Mori is one of the oldest Limiteds still circulating on Roblox: a Latin-phrase skull-and-candle hat released July 8, 2011 for 1,000 Robux with a run of only 26 copies. Today the items leaderboard shows 13 copies left, RAP sitting at roughly 83,000, and a trader consensus value that runs far above that number, making it one of the platform's clearest examples of RAP lagging real demand.

What is Memento Mori?

Memento Mori is a Hat-slot Limited published directly by Roblox (creator ID 1, the platform's own account). The design is a half-shaded, cracked skull with an unlit red candle balanced on top, and its in-catalog description reads simply: "Remember your mortality." The name is the Latin phrase memento mori, a centuries-old reminder of human mortality that shows up across art, philosophy, and literature well before Roblox ever used it.

It launched on July 8, 2011 for 1,000 Robux with a stock of 26 copies, back when Roblox's Limiteds system was barely two years old. Twenty-six copies was already a small run for the era, and it made Memento Mori one of the scarcer items minted that summer.

From 26 copies to 13

Roblox never restocks a sold-out Limited. Once the original 26 units sold, that was the entire supply forever. The only way the count changes is downward: when an account holding a copy gets permanently terminated for a Terms of Service violation or other enforcement action, any Limited in that inventory is deleted along with it. There's no recovery mechanism.

Fifteen years later, roughly half the original mint is gone. Our own tracking shows 13 copies remaining out of the original 26. That pattern is typical for items this old. Pre-2012 Limiteds have had over a decade for accounts to lapse or get banned, so their surviving-copy counts tend to run well below their original stock. For a deeper look at how account terminations and other mechanics shrink supply over time, see what makes a Roblox Limited rare.

That shrinking supply, combined with the fact that Roblox itself was the publisher, is the core of why Memento Mori holds gem status. It's rare today, and it gets rarer by definition every time an account disappears.

A brief, strange chapter: April 2012

Memento Mori has one odd footnote in its history. On April 1, 2012, Roblox's site was compromised by an attacker who gained administrator-level access and altered parts of the platform, including renaming a number of catalog items. Memento Mori's listing briefly showed as "Candle Skull" during that incident before Roblox restored the site and reverted the changes. It's a minor detail in the item's story, but it's one of the reasons long-time traders recognize the name on sight. This is community-documented Roblox history, so treat the specifics as folklore.

Why RAP undersells this item

RAP is an exponentially smoothed average of actual sale prices (see our RAP explainer for the mechanics). On a thin-float gem like Memento Mori, that formula breaks down fast. With only 13 copies split among long-term holders, sales happen rarely, so RAP can sit on an old print for months while trader sentiment moves on without it.

That's exactly what's happening here. Memento Mori's RAP reads in the tens of thousands, but trader consensus values it at a level an order of magnitude higher. That's the gap between "last recorded sale, smoothed" and "what someone would actually have to pay to pry a copy loose today." This divergence is common across the oldest, thinnest-float gems: Rbadam's Smokestack Top Hat, the ROBLOX Tablet series, and other single-print 2011-era items show the same pattern. RAP is the wrong tool for pricing items like this. Treat it as a floor, and lean on copies-remaining and demand signals instead.

How it compares to other classic-era gems

Memento Mori sits in a small club of Roblox-published, sub-30-copy hats from the platform's early years. Ordered by trader consensus value rather than raw RAP, since RAP badly understates thin-float items:

Item Copies remaining RAP
Domino Crown 25 ~5,726,000
The Wanwood Crown 10 ~2,442,000
Memento Mori 13 ~83,000

Domino Crown and the Wanwood Crown both trade at RAP figures that are already enormous, so their RAP tracks reasonably close to what traders actually value them at. High-volume, high-attention gems don't drift far from RAP. Memento Mori is the outlier, a much lower official price tag hiding a value gap because almost nobody sells one. For the full history of those two lines, see our Domino Crown series history and the Wanwood Crown coverage in our Golden Crown series history. If skull-and-bone aesthetics are what draws you to Memento Mori, the unrelated but similarly grim Skull series is worth a look too, and the wider rarest Limiteds collection tracks this whole tier live alongside classic hats generally.

Should traders care about an item this illiquid?

Practically, most traders will never see a Memento Mori change hands. With 13 copies spread across long-term collectors, it's a hold-forever gem that shows up in portfolio flexes and "rarest items" lists more than in active offers. That illiquidity is itself a signal: items this thin tend to be owned by people who understand exactly what they have and aren't selling into weak offers.

For active traders, the lesson is that RAP-based tools miss items like this entirely, and a portfolio heavy in thin-float gems needs different valuation logic than one full of high-volume Limiteds. This is not financial advice. Item scarcity doesn't guarantee future value, and a 13-copy item can also mean you simply can't sell when you want to.

FAQ

How many Memento Mori exist in 2026?

Our tracking shows 13 copies remaining, down from an original run of 26 sold in July 2011. The count only ever goes down, since Roblox never restocks a sold-out Limited and terminated accounts permanently remove any Limiteds they held.

Why did Memento Mori go from 26 copies to 13?

Roblox periodically terminates accounts for Terms of Service violations or other enforcement reasons, and any Limited items in a terminated account's inventory are deleted with it. Over 15 years, that has cut the original mint roughly in half.

Is Memento Mori worth more than its RAP suggests?

Yes, based on trader consensus. RAP is a smoothed average of actual sales, and with so few copies changing hands, it can lag well behind what traders would actually pay for one. Treat the RAP figure as a lagging indicator on items this thin.

What does "Memento Mori" mean?

It's Latin for "remember that you must die," a phrase used across art and philosophy for centuries as a reminder of mortality. Roblox's in-catalog description for the item is "Remember your mortality."

Can you still trade Memento Mori on Roblox?

Yes. As a Classic (non-UGC) Limited, it's tradeable through Roblox's Trade system as long as both accounts involved have active trading access (a Roblox Plus subscription), subject to the standard 2-day hold after a trade.
