Can we sell links from our blog post?

HI friends,

I am a blogger & i write content for my blog. I have written around 200 post for my blog & i have more then 1pr for almost my 70% articles. So i was thinking why not to sell links from my blog posts. I am not sure how many of you are doing it. It's just easy for me to add links in my blog post but can Google penalize me for doing this? Please help me in this.

Can we sell links from our blog post?

Please suggest.

If not too many - you can do it without fear.

@workinseo i have around 50 post with 1 - 3 PR so if i want to sell 1 link from each post then is it fine? How much i should charge for one link? please suggest.
