A photo of a unique blank penny went viral.

The photo was first posted on Feb. 25 by a Reddit user, who captioned it simply "This penny is blank."

The surprising, seemingly rare instance was reportedly due to a minting error. The penny is, according to reports, worth $1 to $2 -- a 10,000 to 20,000 percent profit.

"I’ve never wanted a penny more," one commenter wrote.

"That looks super cool! Nice find there," another said.

The blank coin, according to LiftBump, is known as a blank planchet. It occurs when a coin escapes the machine in a mint.
