⚠ AI-Estimated / Approximate Condition Profile

Cover shows moderate wear consistent with a Silver Age book: slight surface gloss loss and a few faint vertical crease lines running through the central figure, a small white fleck/paper loss near the chest area, and minor edge wear along the top corners. Spine appears mostly flat in this straight-on shot but stress ticks cannot be ruled out from this angle. The book is in a protective sleeve which adds some glare, obscuring fine detail; interior and back cover were not assessed.

// Archive commentary

Superboy #143 arrived in December 1967 as part of DC's long-running Boy of Steel title, produced during the tail end of George Papp's decades-long tenure as the series' principal artist before Bob Brown assumed the art chores in 1969. The issue reflects the standard Silver Age Superboy formula of the period: small-town Smallville drama, secret-identity peril, and the kind of clean, old-school superhero storytelling that defined the character's pre-Legion-crossover era. It carries no first appearance, origin story, or landmark creative milestone, and its historical footprint within the broader DC Silver Age is modest.

Market data for the issue is thin, with recorded sales concentrated at the 9.2 and 9.4 grades and a certified population that thins out sharply below 9.0. Demand tracks the general collector base for run-filling Silver Age Superboy issues rather than any speculative key-issue pressure, and the wide gaps in the FMV table at both the low end and the top of the census reflect a book that trades infrequently outside the upper grades. Pricing at 9.4 and 9.2 has held in a narrow band over recent averages, suggesting a stable but unspectacular collector following.

This issue suits Superboy and Superman-family completists building toward a full run rather than buyers chasing recognized keys. Lower-grade raw copies are inexpensive reading/filler pieces with limited upside, while mid-grade raw examples serve run-builders assembling presentable sets on a budget. High-grade CGC-slabbed copies, particularly at 9.6 and above, command a real premium due to genuine scarcity in top census grades, making them of interest primarily to registry-focused Silver Age Superboy collectors rather than the broader market.
