The NEW ones have generally been about $125.00 for the convention SET. (We've moved past the low run of just 20-30 figures).
Originally, JoeCanuck was $20.00, the rest between $25 and $30.00. It wasn't until 2009 that the exclusives started getting bigger, and for obvious reasons, the price got higher.
Typically, the earlier figures have sold between $300 and $500 - depending on the character, of course.
The 2009 Con set seems to have averaged about $550.00 now, and the 2010 set seems to of settled around the $350/$400 mark.
The 2009 Comic has sold between $30-$60 on ebay, while the 2010 comic can still be had for $10.00 - sometimes less.

The JoeCanuck character TGC card is the one thing you don't see much. Last one I saw on ebay went for $30.00.
The insanely ridiculous prices on my site (
www.bountyhuntertoys.com) are for ones from my own personal collection - and to be honest, aren't for sale. IF someone paid me that asking price for any of them, then I would honestly have no problem parting with them. C'mon, over $1000 or $2000 for a figure? Hell yeah, I'd sell it!

Scary thing is, there was once two people genuinely interested in about 3 of them. One, I think, still is - but obviously can't afford the $5000 price tag I slapped on JoeCanuck.

(Really, not many people that could).
The other reason those are posted there is google. If people go looking for the figures, they stumble upon my site, which leads to the CanJoeCon site - and it encourages people to come here... nifty plan huh?

So anyway, there ya have it.
They're worth whatever you're willing to pay, but they generally do sell in the hundreds.
As for the customs. It's kinda flattering so many people make customs of these characters. But to avoid fakes, each character came with a filecard that was numbered, or the figure was numbered itself - OR, like in the case of Timbit, the character came with something unique that can't be easily re-produced.
Man... that was a ton of typing!
