That '70s Chapeau #70
- Arguably one of the most desirable craft-numbered hats out there

Untradable Manniversary Paper Hat (x2)
- Roughly 40 Paper Hats have been crafted due to a Valve oversight that was fixed fairly quickly. Roughly 4 are untradable. These are two. There has been one untradable Paper Hat on the Outpost, and it sold for the equivalent of 11 buds.

Untradable Manniversary Paper Hat
- The only Paper Hat which was granted by Valve, not to mention that it's untradable as well.

Uncraftable Level 69 Lumbricus Lid
- There are close to no uncraftable Lumbricus Lids, as they are impossible to obtain.
- This is the only Level 69 Lid. Since Level 1, 99 and 100 do not exist, this is arguably the single most awe-inspiring uncraftable Lumbricus Lid that exists.

Uncraftable Level 13 Lumbricus Lid
- There are close to no uncraftable Lumbricus Lids, as they are impossible to obtain. That one has a nice level as well.

Uncraftable Bounty Hat
- An artifact of Steam Support being Steam Support.
- At only 4 samples in existance, one of the rarest uncraftable items of all time.

Level 41 Vintage Foster's Facade
- Some Foster's Facades are odd-leveled. This is the only Vintage one that's odd-leveled.

Uncraftable Hetman's Headpieces, Janissary Ketches, Conjurer's Cowls, Brain Bucket, Dead Cone
- Among the rarest uncraftable hats that exist. Can't be bought from the store at all.

Uncraftable Killer's Exclusive
- This is the only Store Promotional Killer's Exclusive that exists.

Unusual Pencil Pusher
- Nothing particularly special about that one. It just fits with the

Painted Pencil Pushers
- Not paintable.
- The Grey one is the only one of its kind.

Flamboyant Flamenco, Inspecteur, Inspecteur, Pocket Medic
- Level 1 or 2, odd-leveled respectively. Aside from the Level 1 Inspecteur, they all are one of a kind.

Salty Dogs
- These are all existing glitched Salty Dogs

Bonk! Atomic Punch
- Level 9; highest-leveled non-vintage Bonk, odd-leveled.

Killstreak Kits and Fabricators
- Level 0; apparently they cannot be found like this any longer

Special Eyes gifted by my friend MegaG
- Search "special eyes" on YouTube and open the first result if this is not immediately obvious.

Scarecrow

Planeswalker items
- These are the only uncraftable ones in existance

Combustible Kabuto and Sengoku Scorcher #90

Duck Tokens
- Granted by Steam Support and odd-leveled

Lone Star #6

AWPer Hand
