Market Read

What changed

Marketplaces do not agree

What changed

  • Representative price increased 10.5% over seven days.
  • Print-level inventory was roughly flat over seven days.
  • Marketplaces do not agree for this print.
  • 23 tracked sellers for this print.

Why this matters

Price comparison is the main check here: source prices are far enough apart that exact version, condition, and live listings matter before trusting the displayed market read.

What to verify

  • exact printing and collector number
  • current marketplace listing
  • finish shown by the seller
  • condition bucket
  • whether marketplaces agree today
  • whether the representative price matches the copy being compared
