QotD: Stolen Goods

What's the most valuable thing you've ever had stolen?

I had my handbag snatched about 5 years ago now. 

Empty Purse

I was taking my daughter (then 3 years old) to her playgroup and was walking down a lane way to the back entrance of the building when I heard footsteps behind me and felt a tugging on my bag. Adrenalin kicked in and I put up a pretty good fight and made enough noise to attract a few witnesses.  Alas, the guy was physically stronger than me (and probably more desparate) and managed to make off with my bag. 

Apart from the bag itself (which was an Oroton knock off given to me by my brother) and about $100 in cash, the main item of value was a tiny ancient coin (probably Mesopotamian) I had found on the ground visiting some ruins in the Middle East (only had it in my bag as I had been trying to get a coin dealer to identify and value it).  Not sure what the bag snatcher would have done with it as it probably wasn't something that could be easily pawned.  Some water utility workers later found my purse thrown in a creek (along with the purse of an old lady who had been robbed in the same spree).  It still had all the credit cards in it but no cash and, more importantly, no coin. 

Oh well, even though it was pretty special to me, it was still just stuff.  It would have been much worse if I (or even worse my daughter) had been physically hurt in the robbery.
