Looking around many nostalgia items seem to be getting premium money.
Things like:
Old consoles that are still in brand new condition
Old games that are still in brand new condition
Old BMX bikes
Old cars like Japenese, Holden,Fords cars
Do you own anything old and is valuable these days?
I have a BRAND new PlayStation 1 in the box until this day.
Collector's and hard to find items usually go up in value. Then again try not to hoard.
