I took four or five Coursera courses in 2012-2013 while trying to get into the industry. I listed the completed courses on my resume. Employers seemed mildly intrigued but never made a big deal about them, and no one ever asked to see certificates (back then they offered free certificates of completion if you completed the course with a sufficient grade--there was no webcam of typing verification back then, and I think the certificate was just a pdf you downloaded or something). My experience may not generalize, but I'm not sure I'd worry about it. Note: I also had an undergrad degree (math and philosophy, and graduate degree in philosophy, but no school CS experience. No idea how this changes if you don't have any degree).
