I couldn't find any place else to put this. For those people who enjoy big macs, the big mac is turning 50, and to celebrate if you purchase a big mac, you receive a mccoin, that you can redeem the next day for another big mac. Also for people who have the McDonald's app, apparently if you use their app, you can receive your first big mac for $1, and you still get the mccoin.
Apparently these mccoins are collectors pieces, and they are being sold on ebay for $15 a piece. Apparently there are five different versions of the mccoins, and the whole set of mccoins is going for $100 or more on ebay. Hope this helps, Nancy
