How To Get A Free Big Mac At McDonald's

Bitcoin is all the rage these days, but have you heard of the MacCoin? The Big Mac has been a McDonald's staple for 50 years now, and to celebrate the iconic sandwich's golden anniversary, the chain wants to share one with the world. Starting August 2, customers will receive a cool limited-edition collectible metal coin with the purchase of every Big Mac while supplies last.

Then, from August 3 through the end of the year, diners can redeem each coin for one free Big Mac. The coins come in five different designs featuring the art, music, and pop culture elements that represent each decade of the Big Mac's life. This includes '70s flower power, '80s pop art, '90s bold and abstract shapes, early 00's millennium tech, and '10s evolution of communication (hello, emojis).

McDonald's worldwide presence is so broad that the price of a Big Mac is sometimes used to compare currency values between countries. To illustrate this global reach, the coins feature seven different languages: Arabic, English, Indonesian, Mandarin, Portuguese, French, and Spanish. More than 6.2 million tokens will be distributed in the U.S. and 50 other countries.

"When my great-grandfather Jim Delligatti invented the Big Mac at his grill in Uniontown, Pennsylvania, he just wanted to make his local customers happy," fourth-generation McDonald's owner-operator Nick Delligatti said in a release. "August 2 would have been his 100th birthday, and I believe he would be very proud knowing his humble sandwich has made such a lasting impression that people all around the world can enjoy it wherever they find a McDonald's."
