Freddie Mercury
Item: Fish
Cost: $1,500,000
A passionate koi carp enthusiast, Mercury amassed a collection whose value rose to over $1,000,000. Tragically, after his death all but five of the 89 fish —worth up to $17,000 apiece — were killed in a bizarre gardening accident when landscapers at his London home turned off the power for their storage tank. link
