MARVEL TWO-IN-ONE #52

Cover shows strong gloss and vibrant color with sharp corners and minimal spine stress visible; a slight bend is noted near the bottom left corner and light surface scuffing near the barcode area. No major creases, tears, or color breaks are visible on the spine. The book is in a protective sleeve, and only the front cover was assessed; interior and back cover condition are unknown.

Marvel Two-In-One #52 (June 1979) pairs Ben Grimm with Moon Knight for a team-up that also folds in the Fantastic Four, set against a cover pencilled by George Pérez and inked by Joe Sinnott. Interior art comes from Jim Craig and Pablo Marcos, with Jim Shooter editing during Marvel's late-1970s expansion of its team-up anthology line. The issue arrives roughly four years after Moon Knight's 1975 introduction in Werewolf by Night, at a point when the character was still building his solo profile through guest appearances rather than headlining his own title.

The book's market behavior tracks typical late Bronze Age crossover material: ample raw supply and a large certified population (nearly 300 CGC Universal copies) keep values modest through the mid grades, with the FMV curve staying flat in the teens and twenties from grade 6.5 through 8. Values begin to climb meaningfully only at the top of the census, where 9.6 and 9.8 copies command a real premium tied to the Pérez cover and the difficulty of finding pressable, high-grade newsstand copies from this era. Demand is driven more by Pérez completionists and Moon Knight guest-appearance collectors than by any first-appearance significance, since the character debuted elsewhere.

This is a well-collected but non-key issue: raw copies in low and mid grade remain inexpensive and are largely bought by readers filling out Marvel Two-In-One or Moon Knight guest-appearance runs, while top-census 9.8 slabs draw targeted bidding from cover-art and high-grade Bronze Age specialists. Expect steady, unspectacular movement across most grades, with value concentrated disproportionately at the very top of the condition curve rather than distributed evenly across the run.
