How valuable are wikpedia.org links?

Hello,
Recently I found a niche where wikipedia does not have any articles. So I am able to make about 20 articles and will have a link to my money site in "external links" section. I am trying to rank in a small niche with 6 000 GMS but also have an idea to rank more broad in future and even turn into authority site. I think this info is enough for you. So my question is how valuable are those backlinks from wikipedia? I know that they are good thing but on other side all of that backlinks are on Google PR 0.

So what's your opinion about all this?

Wikipedia is a very trust worthy source, we translated whole sections and took us to number one for a verrrrry huge term like hotels, cars, etc... If you need a hand give me a shout we have editor wikipedia account and amazing content writers
