DOCTOR STRANGE #173

Cover shows moderate wear with some minor surface scuffing and light rubbing at the corners, particularly visible at bottom left. There appears to be a small spine tick and slight edge wear along the right border, with colors remaining bright and largely unmuted. The book is in a protective sleeve which adds glare in areas but does not appear to be hiding major creases or tears. Interior and back cover were not assessed.

Doctor Strange #173 closed out the character's original ongoing title, which had carried over numbering from Strange Tales and struggled with sales through the late 1960s before Marvel folded it after this issue. Roy Thomas guided the book's later scripts during this period, steering the Sorcerer Supreme through increasingly cosmic and psychedelic threats that reflected the era's shift toward experimental Marvel storytelling. While not a first appearance or origin issue, it holds a place in Doctor Strange's publishing history as the endpoint of the character's initial solo run, one that would not resume under its own numbering until the 1974 revival.

Market activity for the issue tracks a fairly typical Silver Age curve: values stay modest through the mid grades, climb gradually into the 8.0-9.2 range, and then rise sharply at the top of the census, where certified copies are scarce and demand from grade-focused collectors intensifies. Sales volume is healthiest in the 9.0-9.4 tier, suggesting most collector interest centers on well-preserved but attainable copies rather than the handful of higher-grade rarities. The absence of any 9.8 sale on record, against a small population of six census copies at that grade, points to a book that rarely surfaces in top condition and commands a real premium when it does.

This issue suits completists of the Doctor Strange character and Silver Age Marvel run-builders more than speculators chasing a single marquee key. Lower and mid-grade raw copies move steadily at modest prices, reflecting reading-copy demand rather than investment pressure, while high-grade certified examples draw a smaller but more competitive pool of buyers assembling complete runs of the original series. Because of its status as a series closer rather than an origin or first appearance, its ceiling remains tied to condition scarcity rather than character-driven key-issue demand.
