The gens Marcia (both patrician and plebeian families) claimed descent from the legendary kings Numa Pompilius and Ancus Marcius. From the plebeian Censorini C. Marcius Rutilius Censorinus was appointed consul in 310 BC - and became the only person to have held the office of censor twice. The moneyer Marcius Censorinus, a Marian supporter, is said to have killed the consul Octavius during the proscriptions and was later defeated by the Sullan army and executed in 82 BC.

The reverse type of this denarius commemorates the founding of the Ludi Apollinares in 212 BC, at which horse races took place. This event was allegedly foretold by a soothsayer, one Marcius. The reverse depicts a horseman (desultor) jumping from one horse to another.
