  Coma is frequently used as the archetype z~0 galaxy cluster to compare higher
redshift work against. It is not clear, however, how representative the Coma
cluster is for galaxy clusters of its mass or X-ray luminosity, and
significantly: recent works have suggested that the galaxy population of Coma
may be in some ways anomolous. In this work, we present a comparison of Coma to
an X-ray selected control sample of clusters. We show that although Coma is
typical against the control sample in terms of its internal kinematics
(substructure and velocity dispersion profile), it has a significantly high
(~3sigma) X-ray temperature set against clusters of comparable mass. By
de-redshifting our control sample cluster galaxies star-formation rates using a
fit to the galaxy main sequence evolution at z < 0.1, we determine that the
typical star-formation rate of Coma galaxies as a function of mass is higher
than for galaxies in our control sample at a confidence level of > 99 per cent.
One way to alleviate this discrepency and bring Coma in-line with the control
sample would be to have the distance to Coma to be slightly lower, perhaps
through a non-negligible peculiar velocity with respect to the Hubble
expansion, but we do not regard this as likely given precision measurements
using a variety of approaches. Therefore in summary, we urge caution in using
Coma as a z~0 baseline cluster in galaxy evolution studies.
