Have a load of coin sized stickers printed, and stick them on a load of assorted coins in a bag. Then use those coins to purchase groceries in supermarkets, and pay at the do-it-yourself tills. Hopefully the coins will be recycled, and dispensed to shoppers who use cash for purchases.
I believe it's illegal to modify currency. Also, those coins would jam up modern sorting machines / self-serve checkouts..
Throwing coins out of airplanes?

I knew making this thread would be worth it.
That's an interesting idea about taping advertising to coins though... Offtopic: I have a feeling the United States is going to do away with coins in the near future.
Is it illegal to put emboss a bill? (it just raises the surface of the paper with no ink) I believe it would be covered by the First Amendment... We could absolutely throw paper out of planes safely.
Stickers are not the way to spread info about crypto currencies.
It makes me SUPER happy to see a Bitcoin-related sticker in the wild. Regardless of what brand sponsored it.
