Is the Pioneer model no. SK-550 Boombox really worth as much as they say it is?


I have this boombox and im kinda dumb founded at how much there going for. Any insight on the subject would be greatly appreciated.

This is a common problem across MANY hobbies..Low life sellers list items on Ebay at massively inflated prices..Even if item doesn’t sell that price is now in digital land.Someone else researches the prices & these inflated prices are factored into the average,wala, FAKE "value"is born...
on ebay, in the last 2 months, only 1 has actually sold, for $225...
