Item: valuable vintage trash can with valuable vintage stains
Item: the International Prototype of the Kilogram, aka le Grand K, aka the Urkilogram, a platinum-iridium alloy cylinder whose weight is one kilogram. Not that it can be weighed to be roughly equal to one kilogram, but a piece of metal whose weight (up until 2018) was the definition of how much a kilogram is.
Item: the world's largest pecan (according to the owner)
Item: the World's Stinkiest Sock, developed originally as a stunt by a laundry company but stolen before it could be cleaned. Retrieve it quickly before it can be used for evil!
Item: the Eye of Argon, the titular “many-fauceted scarlet emerald” from the famous fantasy story by Jim Theis. It’s the “My Immortal” of fantasy novels, so I definitely recommend reading it when you have time to kill; it’s so bad scifi/fantasy cons used to have contests to see who could read it the longest while keeping a straight face.
