What is the most valuable or rarest thing you own?

For me, it would be my working 2005 furby (with a very beaten up box) that I just got yesterday. I'll post an image of it later on, idk when <33

But I'm curious as to see what everyone else collects and values, whether it's emotional value or monetary value.

Personal value: My childhood PS2 or plushies

Rarity: Subseven's black album CD or Silent Hill for PS1

Price: A house 

my Parachutes CD signed by Frank Iero OR my Bullets CD...

my giant 300$ Labubu my ex gave me as a joke-...

Most valuable (money wise): My cochlear implants. Replacements costs thousands of dollars and so do spare parts. I take very good care of them and each version I've had only breaks down when they reach the end of their lifespan (5-6 years usually). I did have to get one of my magnets inside my head replaced because it broke when I got hit by a sled at full-speed sometime in 2010/11. 

Personal value: I have two paintings made by a niche artist named Lori (the name signed on the canvases) that I've owned for as long as I can remember, always hanging side by side in my bedroom. They are in good condition but very old (I think they were made sometime in the early to mid-2000s, but I'm unsure).

I am pretty lucky yo be one of the few owners of a first edition copy of the worlds first loose paged book, composition no.1

newspaper from 9/11 or a newspaper from rhe moonlanding in '69

MAYBE my camcorder? but I think those two beat it out. Most valuable is probably my camcorder though

I think it might be the substance soundtrack on a record but idk

idk if it’s worth anything but i have a 1912 newspaper from when the titanic sank

a stained glass window panel from the victorian era. it was sitting under my grandparents bed for decades and gifted to me on my 18th birthday

my lotms dvd with the cd!!!
