Is Amazing Spider-Man #300 Trending Up or Down?

Amazing Spider-Man #300 is trending slightly UP — our data shows CGC 9.8 copies are up about 2% over the last 90 days, with a recent CGC 9.8 sale hitting $2,899 (July 4, 2026), above our FMV estimate of ~$2,316 for that grade. Lower-grade copies are also moving briskly: a CGC 6.5 sold for $350 and raw copies have been selling between $330–$521 in early July 2026. It's a healthy, active book — not a runaway spike, but steady demand for the first full appearance of Venom keeps the floor solid.
