Mercury

Few characters can claim roots as deep as Mercury, who burst onto the scene in the very first issue of Red Raven Comics in 1940 — a true Golden Age original brought to life by R. Louis Golden at the dawn of Marvel's storied universe. Spanning an remarkable nearly eight decades of publication, this character has kept extraordinary company over the years, sharing pages with legends like Captain America, Namor, and Spider-Man across titles including Avengers / Invaders and Marvel Super-Heroes. That kind of enduring presence — rubbing shoulders with the absolute pillars of Marvel history — speaks to a character woven into the very fabric of the publisher's legacy. For collectors with a taste for the rare and historically significant, Mercury is a genuine piece of comics archaeology worth seeking out.
