A black hole with the same diameter as a nickel would slightly beat out Earth's mass of around 13 x 10^24 lbs (6 x 10^24 kg). Assuming it appeared in your pocket or wallet, its pull would impact everything from the entire planet to, potentially, objects in the Asteroid Belt. Even a black hole with the mass (not the diameter) of a nickel would have far-reaching effects. Though the black hole would be far, far smaller than an atom, it would release more energy than an atomic bomb as it radiated its mass away.
