What is exactly ‘collectable’?

Stern games do not really go up in price, even when they are ‘limited editions’
There were special ‘Monopoly’s’, probably worth more than normal, but still less than what was originally paid for them
Same with the signed ‘Elvis!’
Spidy Black seems to have fared a little better, but with limited numbers being sold, hard to tell
LOTR Le, to early to tell, but with poor gold plating, missing figurines, and an underwhelming backglass, I doubt they will do much more than hold their value

Avatar was a bit average to begin with, I cannot see it being a ‘must have ‘ in peoples collections
(plus the movie sucked )
