See for yourself - like toomanybeersies says, they should have an orange roe (boys and girls both have them - scallops switch sex as required), attached by some stringy material. The roe has a flavour and texture different to the white meat of the scallop, which is the muscle used to open and close the shell. The white meat should have a firm and homogeneous texture - fakes tend to have textured lines through them, but not always.
