There will be a whole lot of them - more than 6.2 million - and the MacCoins will feature artwork that throws back across the decades of the Big Mac's history at McDonald's.
"The Big Mac is a cultural icon and what better way to celebrate its continuing status than to issue a commemorative coin", says Henry Nienhuis, President of the Royal Canadian Numismatic Association.
Starting August 2, customers will receive a cool limited-edition collectible metal coin with the purchase of every Big Mac while supplies last.
And that seems to be the case with the McDonald's Big Mac.
The coins feature five unique designs, each representing a decade of the legendary sandwich.More news: China's Xi warns of no winner in Trump trade dispute

Customers can then cash the coins in for a free Big Mac starting August 3.
The MacCoin will be redeemable at 14,000 USA locations so chances are there'll be one close to you that'll take what the fast food empire is hailing as the "first fully food-back global currency". "Since 1968, Big Mac fans across the greater Philadelphia area have enjoyed two all-beef patties, special sauce, lettuce, cheese, pickles and onions on a sesame seed bun with a flavor that's just as craveable and delicious today".
"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", said Nick Delligatti, fourth-generation McDonald's owner-operator and great-grandson of Jim Delligatti, the inventor of the Big Mac.
The coins also happen to go into circulation three days before what would have been the 100th birthday of the inventor of the Big Mac, a meal that originally sold for $0.45.
Jim Delligatti died previous year.
