Positrons (anti-electrons) are hitting you right now from cosmic ray
showers. In high energy cosmic rays, the ratio of observed
antiprotons to protons approaches unity. However, there is no
observation of macroscopic anti-matter, nothing bigger than a single
anti-hydrogen atom as far as I know.
Hannes Alven speculated the nearest star could be made of anti-matter,
and we would have no way to know. The strongest evidence against this
is that not a single anti-helium cosmic ray has ever been detected,
but even the lower limits there aren't that low on a cosmic scale.
Hopefully the AMS (Alpha Magnetic Spectrometer) will finally be flown
to push that lower limit even further down or detect that one golden
antihelium particle.
They (antimatter) have mass and respond to gravity, but their active
gravitational potential (ability to attract other matter) has never
been measured.
