There is a darker side as well, some pull this stunt to inflate insurance and declaration values, citing the faked ebay auction...

They also have been known to use this sort of thing to drive prices of collectibles higher as well.

I would think the insurance companies are wise to the prank, and maintain their own tables of value.  you can sometimes jawbone the local agent into your figure or a nice compromise if you have documented special values on your unit (HW101 once owned by President Fillmore N4GOP, documented.)

About 30 years ago, when beer can collecting was briefly hot, some guy ran ads in newspapers around the country offering to pay $100 or more for Billy Beer cans. Then he put his cans up for sale at $10 each.

Billy Beer cans were and still are about worthless.
