Selling Sketch Cards?

[AndrewJones]

I'm posting this here because I see a lot of Artcasters doing sketch cards. I've just started to get into doing cards and am a ways away from actually taking commissions.

That said, I wouldn't mind making a couple bucks

So I was thinking about throwing cards up on eBay and seeing what happens. Do any of you have any luck with that? Is $10 too high to start off?

Here's my cards so far: http://atlantajones.deviantart.com/gall ... etch-Cards

Most are my modified "business" cards, but anything I put on eBay will be a standard-sized trading card.
