The not so extraordinary globular cluster 037-B327 in M31
A velocity dispersion has been measured for the luminous globular cluster M31 037-B327, claimed to be the most massive star cluster in the Local Group and to be a young "super star cluster" that has survived to an old age. M31 037-B327 has a mass comparable to that of M31 G1 but not significantly larger. Although near the upper end for the mass distribution of globular clusters, it is not an unprecedented extraordinary object.
