Lave it to McDonald's to continually innovate while still staying grounded in its roots.

America's most famous burger, The Big Mac, is turning 50 years old, and McDonald's wants to feed you for free.

Mickey D's has developed its own form of currency called the MacCoin.

The MacCoin can be obtained by simply purchasing a Big Mac starting this Thursday August 2nd. When you purchase your burger, you'll receive a MacCoin good for another Big Mac starting this Friday through the end of August.

The MacCoins will have different insignia's marking the evolution and decades the Big Mac has been available:

•The ‘70s: Showcasing the decade’s flower power

•The ‘80s: Alluding to pop art

•The ‘90s: Defined by bold, abstract shapes

•The early ‘00s: Specifically focusing on the technology that was at the forefront of the turn of the century

•The ‘10s: MacCoin calling attention to the evolution of communication

The Big Mac is one of America's most iconic sandwiches, so why not enjoy one for free?! This entire deal is basically buy one, get one free Big Macs, which is pretty sweet.
