  • Print-level inventory declined 6.2% over seven days.
  • Marketplaces do not agree 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

Sources, methodology, and disclosureOpen

NeoPrice and Pricing Confidence use the existing NeoCardAlpha methodology. CardTrader is the inventory source, TCGplayer is the primary pricing source, and Card Kingdom is validation-only.

NeoCardAlpha may earn a commission from certain marketplace links.

Card Kingdom retail validation is visible when a matching product is available, but it remains a validation source.
