Condition & Value

Condition Grade

Fine (CGC 6.0)

Condition Details

Visible horizontal color-breaking crease across the middle section; spine stress marks; corner blunting on the bottom right; minor edge wear and light surface scuffing visible through the polybag.

Estimated Market Value

Raw: $5 - $15 | Graded (9.8): $75 - $120

Recent Sales

Raw copies typically sell for approximately $10-$15 in mid-to-high grade. Higher grades are scarce due to the low print run of late-series issues.

Grading Recommendation

Not recommended for professional grading. The visible mid-cover crease significantly lowers the grade potential below the point where a return on investment is viable, as this is not a key issue.

Notable Features

Low print run (common for later issues of licensed kids' comics); features Mandark; UPC barcode present; DC 'Bullet' logo.

Authentication Notes

Appears to be an authentic first printing. The paper stock matches early 2000s DC glossy covers; registration and color saturation on Mandark and Dexter's outlines are consistent with period printing standards.
