Is this Cypraea leucodon or Cypraea vitellus?

It's okay. Hahahaha.... Besides, I did not bought that shell but I've obtained that shell in a beach (alive).
This is a Cypraea vitellus. When you make a photograph of the teeth, you will have absolute certainty. Cypraea leucodon is more bulbous than vitellus and most distinctive are the much coarser teeth...
