What's the value of?...

[StayFree( ' 3')]

Just recently moved and during the process I rediscovered a lot of stuff I forgot I had, some of which I have no clue on what they're worth.
For now I'll start with these two:


Space Channel 5 Press Kit





This is the only one I've ever seen complete. Still have the Dreamcast mailer it came in.


Loco Roco Promo Inflatable








This is the only information I can find on this...

Appreciate the help guys. Hopefully when I have the time I'll be able to post some pieces of my collection.
