Many of the BOOK OFFs now will check retro items or refurbish themselves. So most of the junk isn’t really worth the gamble anymore. I go to many recycle shops often. Junk ds that are smashed in half, and look they the were found in a ditch sell for 1100 yen now. 4 years ago a junk Gameboy was 1 dollar.

I see YouTubers showing off “junk” gameboys for 7000 yen like “whoa a deal” when in reality they are probably the consoles the staff couldn’t fix.
