As a very rough guide, and keeping in mind how subjective pricing is, here is a rough guide. As a side note, if you are not a collector I understand how you can think that by buying hundreds of packets and spending over $1000, a collection is then worth that. The reality is that only higher end numbered cards really maintain and appreciate in value.
08 Champions
A folder and complete base set are still readily available for between $30-$40
The parallels from this release tend to be more sought after and generally fetch $0.75 - $1ea
The foil signatures are about $3-$4ea.
The sketch cards are in the $4-$8 each range depending on team / player
The gems are about $8-$12ea
09 Champions will be very similar in pricing
The jersey cards are $0.50ea
I see a Canberra Double Trouble card in the folder which were quite hard to get, 1:4 boxes from memory. These were continued in 09 Classic and despite not being numbered are limited to 300 each. They should be worth more but rarely go beyond $40 at auction.
If you want to sell, you are best separating into team lots at a minimum. If you auction as one lot, you will struggle to get $150.
Good luck !!
