Supermoon: Fun fact

There have been lots of articles about the 'supermoon' in the past few days, see e.g. the BBC, which is basically trick photography, you just photograph the Moon behind a very distant object and enlarge the image.

Glossing over the fact that the Moon can appear a couple of per cent smaller or larger depending where it is on its elliptical orbit, without looking, which of the following objects, held at arm's length, appears to be the same size as the Moon?

A tennis ball,
A golf ball,
A ten pence piece (or a US quarter or a one Euro coin), or
Your little fingernail?
