Thinking of magic items that can be found without giving the players too much gold, I came up with a list of 10 items of little actual value (so of about common to lower uncommon value) but that are fun and may lead to interesting very specific uses, and fun rp:
Amulet of Hindsight- You get advantage on checks regarding events in your past.
Ostentatious Broach- When worn, the wearer has the effects of fairy fire cast on their self, with no additional range.
Misty Key- Once per long rest, the user can turn to a mist form for six seconds, during which they may fit through any surface space a creature one size smaller than you can pass through.
Lagged Dagger- A cut by this dagger shows thirty seconds after it strikes. Does normal damage five rounds after striking, and the damage is considered magical.
Adjustable Weights- A small lightweight anvil shaped trinket. Once per day, it can be activated with a command word, upon which it instantly begins to weight half a ton until deactivated or one hour passes.
Bracers of Speed Reallocation- Once per long rest, you may use all of your movement to make an extra melee attack. Requires atunement.
Cloak of Misplacement- An item placed in a pocket of this many-pocketed cloak disappears and appears in another pocket once the hand placing it is removed.
Orb of Illusion- Once per long rest, this orb can be activated to take the effects of minor illusion, cast on the orb. This effect can be activated in your hand and thrown, the illusion activating on impact.
Inverse Umbrella- When opened, light rain begins to pour down from the inside of the umbrella. This effect can last up to fifteen minutes per day.
Glasses of Lightvision- When worn, the user has the effect of darkvision when in bright light (can see black and white for 60ft).
