Odds of Pulling an Auto vs. Relic?

Sethro

Does anyone know the odds of pulling an autograph card versus a relic card in modern baseball hobby boxes? Over the past few years I have purchased around 20 hobby boxes of Heritage and base cards and every box guarantees an auto or relic. In 20 boxes I've only received relics. And crappy relics in my opinion. (No offense to Jayson Werth or Aramis Ramirez.) So although 20 boxes is not a huge sample size, it just has me wondering the odds of getting an auto. Thanks!

On average, I'd say 10 relics:1 auto for a "base" product like Heritage, Topps, etc.
