USDGC ROCS and thrower rocs and spectator rocs

I'm just curious on why no thrower rocs from any year are not on any collectors guide. i have 2 thrower usdgc rocs from 2008 and 2009 but the are not on any guide in champion roc.com or usdgc.com. any one know why this is? another question i had is why are a lot of guides missing spectator rocs as well?

Spectator rocs are numbered and can be found on zonedriven.com. they are not part of the original release.   The spectator rocs are given out at first come first serve at the tourney in Oct. The throwers are just that, ment for throwing.  They are for sale a few months after the release of the USDGC rocs at disc golf u.  Some can be worth money if rare color or stamp.  The throwers are not numbered and do not come with a card.  I think they are made from the left over plastic from the USDGC rocs.  Thery just dont have the time to keep track of all of it.  This also keeps the price higher for the USDGC rocs.
