From TF2 Wiki
All items have an associated quality or rarity. The quality of an item determines the color of its displayed name and influences its perceived trade value.
The names of item qualities, and the term "quality" itself, are derived from the game files.
The Normal quality is assigned to Stock weapons. These are the standard weapons that all players start with and are not stored in the backpack. Therefore they are the only available weapons if the game cannot connect to Steam. Unique variants of these items are created when using a Name Tag or Description Tag with a Stock weapon, which are seen by checking the "Show Stock Items" box in the backpack view. If you rename your item it will become tradable
Unique is the quality assigned to items which can be found through random drops during gameplay, obtained through achievements, crafted, or purchased from the Mann Co. Store. As such, Unique is regarded as the "default" quality for items.

Vintage was introduced alongside the Mann-Conomy Update, in which certain items were assigned this quality to increase their appeal in trading; however, they bear no functional difference to their Unique counterparts. In some cases, items that have been re-granted to users by Steam support were assigned Vintage quality.

The Genuine quality was originally introduced alongside the RIFT promotion. Genuine quality is used to distinguish items obtained as part of a cross-game promotion, opposed to items gained via other methods such as random drops or crafting. There is no functional difference between Genuine items and their Unique counterparts.

The Strange quality was introduced alongside the Uber update, available through unboxing a series 19 and onward crate. They have a kill count that shows the total amount of kills obtained with the weapon. The items will have their name changed dependant on how many kills the weapon has. For instance, after getting ten kills the gun will change from 'Strange' to 'Unremarkable'.
On another note: If you trade a strange item with kills on it, the kills will then be reset, becoming 0 kills and will get the "strange" name again. If you craft two strange weapons it will not produce another strange, it will just give you metal.

Unusual hats are hats with an attached particle effect.
The only methods of obtaining an Unusual hat are by unlocking a Mann Co. Supply Crate with a Mann Co. Supply Crate Key, or via trading. Unusual versions of the hats contained in a Festive Winter Crate could also be obtained by unlocking the crate with a Festive Winter Crate Key during the Australian Christmas event.
Scream Fortress Update
- Main article: Scream Fortress
Two new items with the Unusual quality were introduced with this update: the Haunted Metal Scrap and the Horseless Headless Horsemann's Headtaker. Besides bearing the Unusual quality, the Horseless Headless Horsemann's Headtaker has no discerning attributes from the Eyelander.
Items bearing the Community quality are specially granted by Valve to individuals who have made significant, valuable contributions to the Team Fortress 2 community. Community items have the Community Sparkle particle effect attached and an additional description string set to "Given to valuable Community Contributors". Community items derived from certain Stock weapons receive an additional boost to their Phong shading exponent, resulting in the weapon having a more glossy appearance.
Stock Community items that existed prior to the introduction of name and description tags are derived from their original Normal variants. This makes them unable to be described or named, however newer variants are derived from the Unique variants; and behave as expected.

The Self-Made quality is assigned to items specially granted by Valve to their creators. Like Community items, they have the "Community Sparkle" particle effect attached and an additional description string set to "I made this!". See the Contribution page for when the items were added in-game.
Valve items are given to Valve employees. In some cases they have the Flying Bits particle effect attached. Because of their nature as developer weapons, some Valve items possess stacked attributes as seen in the backpack example; however, these additional attributes are not part of the Valve quality itself. The Valve weapon shown in the backpack example is Robin Walker's Rocket Launcher. No you cannot find these weapons
