This is a Disney Cast Member Lanyard Pin.

It could only be acquired by trading with a cast member from their lanyard.

It features Hercules face and left arm on this round blue pin.

Hercules is flexing his muscle and looking at it with pride.

Part of his hand, wrist and elbow protrude slightly off the pin.

Right over Hercules muscle it reads "Disney's HEROES" in gold letters.
