Sub-Mariner #1 CGC 3.0 – 1968 Marvel Silver Age Premiere Issue

Sub-Mariner #1 is the premiere issue of Prince Namor’s 1968 Marvel solo series, presented here as a CGC graded 3.0 Silver Age slab with Off-White Pages. A key Marvel issue from the late 1960s, this book launched Namor into his own ongoing title following the transitional Iron Man and Sub-Mariner #1 one-shot.

This issue features a Roy Thomas story, interior art by John Buscema and Frank Giacoia, and a striking John Buscema and Sol Brodsky cover. The CGC label notes that the story continues from Iron Man and Sub-Mariner #1 and that the origin of Sub-Mariner is retold, giving this book strong key relevance for Namor, Marvel Silver Age and early solo-title collectors.

Why It Matters

Sub-Mariner #1 is a key launch issue from Marvel’s 1968 expansion period, when major characters were moving out of anthology titles and into their own solo books. For Namor, one of Marvel’s earliest and most enduring characters, this issue marks the beginning of his first major Silver Age solo run.

The book also links directly to Iron Man and Sub-Mariner #1, making it especially appealing as part of the 1968 Marvel transition sequence alongside Iron Man #1. With the origin retold and John Buscema’s classic cover work, this is a strong entry point for collectors who want a presentable, more affordable copy of a genuine Silver Age Marvel #1.
