Nobody expects the two-headed nickel!
Observe, 1 of the nickels in the photo is a regular coin, the other is our 2-headed nickel.
The reason you probably can't tell the difference, is that the two-headed nickel is made from real nickels! It's the same thickness as a regular nickel, and the edge looks the same too! It's about impossible to tell. It's just a little "insurance" to make sure the toss goes your way. Unless you drink too much and holler "TAILS!"
