I'm guessing you're in the US not the UK so I can't comment on legal aspects (it's illegal to discriminate on the basis of age in the UK, that's not to say it doesn't happen...).
So, focus on your skills and what you can offer an employer. A lot of employers mistakenly think they want "bright youngsters" when the reality is they'll probably only stay for a couple of years whereas, statistically speaking, over 40s/ 50s will stay for longer giving more stability to teams.
I'd suggest a skills based CV/ resume so you can sell a potential employer on your skills and help get your foot in the door. I wrote a hub on it but I'm new around here and understand it's bad etiquette to post a link to it. I'm happy to send you a copy of a skills CV if you want - just let me know.
Good luck. :-)
