What's the most valuable thing you've lost?

I'm talking in terms of an actual item so not "the love of my life" or something corny like that :P . For me it would have to be my official PS3 bluetooth headset. It worked great for gaming so I thought I'd use it for my phone and again it worked great... problem is it fell out of my pocket while at school so I kissed that thing goodbye, no I have to use a cheap LG headset. 

The love of my life! ... DAMNIT! WHYYY! ..  
 
Well ok in all seriousness, nothing pops up in my mind. 
I take care of the valuable stuff, I guess. 

Weeks of work in a HDD crash. Still kinda mad.
Also the love of my life, duh.

Love of my life as well.  Um, let's see. I lost an MP3 player before which totally sucked since this was back in the day before iPods were cool and that thing was super expensive (But only held like 200 songs). That's really it, I'm usually pretty damn careful with my electronics/valuables. 
 
I have a friend who lost a Rolex watch in England which  his dad gave to him...we give him so much shit about it to this day.

The worst would be my calculator in high school. Other than that, I don't think I've lost anything of significant value.

Honestly, a pillow case my mom made me. I took the pillow with me on a speech and debate trip I was judging on and forgot it at the hotel.

Aside from the love of my life? Hmm... I  don't loose stuff.. I check and double check my stuff all the time to be sure I haven't.
Though my XPS laptop for 2,5 grand broke so I guess that could count as a "loss".

Well, besides the love of my life, I've probably lost a lot of change. And I lost Boone on Fallout: New Vegas once, but I found him again. I want that damn change back!

I was eating at KFC and took my $250 (cdn) bulova watch off for some reason and left it on the food tray, then we left to a new years eve party. That night I was asked what time it was.

I then knew what a grievous error I'd made.

The love of my life, but besides that it probably has to be a wallet with $450 in it.

I've always been pretty careful with valuable stuff. Once I lost my GameBoy SP, but I got it back about a month later.

I lost a Nintendo DS once. 

Lost an autographed photo of Wayne Gretzky that he signed in his first year on the LA Kings.  My mom got it for me; she is a pediatric nurse at the hospital that Gretzky and his wife had their first child.  I threw it in a closet where I kept all my toys and other childhood junk because I wasn't a fan of hockey, and have been unable to find it in my parents' house ever since.
 
It's probably worth a little bit of money now.

I rarely lose things. I actually find things more often than I lose them, like this time I found some dudes wallet with at least $450 in it. That was a good day.

My W-2

Was going to come in and say my dad back in '06, but I will just assume loved ones are included in "something corny like that"
 
For material possessions, some Yu-Gi-Oh cards were stolen way back when that was the cool thing for kids to collect.

" The worst would be my calculator in high school. Other than that, I don't think I've lost anything of significant value. "

Does having something stolen count as losing it?
 
If so, I had a 32" LCD TV stolen from my apartment a few years ago.
However, having the love of my life stolen away from me was way worse.

My virginity :-)

Not trying to sound like i hug trees for a living, but i honestly don't really give a shit about physical possesions.

" @ClaritySam: Well giving it to your mom doesn't mean you lost it....        I'm joking btw please don't take it personally :P "

OH SNAP IT'S ON NOW SON! :-) "

But I'm Over It 

" @FlyingRat: I 100% understand and am in kind of the same boat. I was just asking for say the most valuable thing maybe in monetary value.  "

" My virginity :-) "

Probably my heart, seriously, you should try talking to me now... i will make you cry. 

In Kindergarten, I lost a Blue pendant that was handed down generation after generation while in school. :/ 

Does jpeg images count? If so, then a couple ones last year which were taken during the summer that reminds me of some great memories. They were lost during some transfer from a macbook to a PC. But I can't remember anything highly valuable in money.

Nothing comes to mind.

Love of my life here as well, not joking about it though.

I left my DS on the bus once back in 2006. Really made me sad.

I lost my wallet in a bar in Honduras. Actually, I left it on the back of a commode. My driver's license, Navy I.D. and 250 dollars all gone.

An autograph I got from a real Shaolin monk. Somewhere on a bus in North London...
 
Also, PSP batteries, DS styluses, and the love of my life. Respectively.

I also have hard drive woes.  The hard drive I used for over 2 years in college completely crashed on me at the end of a video editing class.  It had all of my college work on it, and I never recovered any of it.  Being in a 3 year college meant that I was on pure panic mode for the final 9 months of my education, since it all culminated in a portfolio review that represents the best of your work.  So yeah, I had a lot of work to do.
 
Despite that, I did pass on my first time through. =)

Fuck, some people already said virginity. 
 
Uhh, but yeah, someone stole my graphing calculator in high school. Just replaced it with a newer model. I didn't pay for it so whatever.

One time I went out and bought this limited edition 686 x Dakine snowboarding jacket/backpack combo thing for like $500.  I went to a part at a good friend of mine's house a week later and left the backpack with all my shit in it on top of my jacket which was hanging on the back of a chair upstairs.  I went downstairs for literally 3 minutes to grab a drink and see who was there already.  When I came back up my backpack was there but the jacket was gone.  I literally cried.

I lost (or was it stolen!?) my graphing calculator in high school, which made math 12 a huge bitch and I got a lot of trouble for it.

does the love of my life count ?

I've dropped £20 before but Im struggling to think of anything else, I guess Im pretty careful.

Playstation 2, well it was stolen but I still lost it from my posetion.

• PS3 official bluetooth headset.
• Gameboy Color with about 7 or 8 games (they were all in the same small case) when I was much younger.

I once lost my brother's £900 laptop by leaving it on a train.

A friend

I don't know; I take pretty good care of my stuff

I've lost not one, but two iPhone's. 
 
The first I think I left in a taxi, the second I think I left in the cinemas.
