Notes

• Active listings and historical observations are source-grounded. Dashed monthly values are provider-modeled estimates, not observed listings or transactions.
• Modeled estimates cover the current month and previous 12 months and require a grounded observation from the same provider.
• Prices are USD per single item and exclude shipping and tax.
• Three current-listing queries completed. Three qualifying direct listings were found, but all are on one domain; the two-domain stopping target was not met. Confidence is limited by source concentration and differing wear grades.
• The initial median is USD 150; all three asks fall within one-third to three times that median, so none were excluded as outliers.
• Dates on active observations represent the requested verification date, not seller publication dates. Search-index freshness varied.
• Sold-price histories, market estimates, out-of-stock products, non-holo cards, damaged cards, and category pages were excluded. No historical query was used because no plausible direct historical asking-price archive was identified.
• Modeled values are estimates, not observed historical prices; pricesUsd follows the requested month-date order.
• openai validation accepted 16 of 16 raw points.
• Search used: 3 current-listing queries. The optional 4th historical query was not used because the results did not point to any direct archived-listing or asking-price-history source.
• Rejected: ebay.com/itm/397062477150 (correct card, but the result showed no price), ebay.com/itm/147548047077 (graded PSA 8, not raw played, and no price shown), ebay.com/itm/146718646707 (no price shown, and the listing was about 461 days old), poromagia.com (price in EUR only, condition not shown), cashcardsunlimited.com (no price shown).
• eBay search pages showed raw used asking prices that cannot be used because they come from search pages, not item pages. Examples: <cite index="20-4">Squirtle 64/100 EX Crystal Guardians Reverse Holo Stamped Pokemon TCG Pre-Owned $109.99 Buy It Now +$6.34 delivery</cite> and an MP-condition listing at $180.00. These were not accepted.
• PriceCharting shows recent sold prices, not asking prices, so they were also not accepted. Example: <cite index="26-10">Squirtle - 064/100 Pokemon EX Crystal Guardians Reverse Holo Stamped HP 64/100 [eBay] | $90.00</cite>.
• Confidence: none. A grounded anchor would need direct item pages, for example eBay /itm/ pages or TCGplayer listings filtered to Lightly or Moderately Played reverse holo, that show a price.
• anthropic validation accepted 0 of 1 raw points; rejected invalid_modeled_series=1.
• Fewer than three qualifying direct active listings found meeting all strict per-item criteria; assessed with low confidence using the single qualified normal-channel ask.
• Flat 13-month modeling applied in accordance with rules requiring at least two qualified historical asking price observations to support a directional trend.
• gemini validation accepted 14 of 14 raw points.
