Diamond & Pearl Era Card Prices: 20 Sets

The Diamond & Pearl era ran from May 2007 to February 2011 and our catalog holds **1,949 cards** across its twenty English sets, every one of them priced, asking **$42,920.75** in total on 2026-09-23. The era is a similar size to Sun & Moon in money and half its size in cards, so the median card asks $1.62 rather than 45 cents. But the real difference is what grade the market trades. **339 of the 1,949 cards carry a recorded PSA 9 sold median and no PSA 10 one. Seven carry the reverse.** In this era the nine is the product.

Every set in the era, dated where a release date is recorded. The four POP Series sets carry no recorded release date in our data and are printed as such rather than dated from memory; they are also the ground of POP Series Pokemon cards value, which does the promo-versus-pack analysis this census deliberately does not.

Read the last two columns across the whole table and the era's character is visible set by set. Secret Wonders has 22 cards with a recorded PSA 9 sale and none with a PSA 10 sale. [Diamond & Pearl](/research/set-screen/diamond%20%26%20pearl) has 15 and none. Only Call of Legends and Triumphant get into double figures on tens, and Call of Legends is a 2011 set of holo reprints that grades far better than the rest of the era.

One link note: [Diamond & Pearl](/research/set-screen/diamond%20%26%20pearl) has no `/set/` page, because no set-value series exists for it, so the set screen is the surface that works. Every other set in the table resolves at `/set/` and each title was fetched and read back.

Here are the eleven dearest of the 339, which is the top twelve with Glaceon 98 removed. Glaceon is counted in the 339 and is left out of this table alone, because its PSA 9 median moved from $3,002.49 on 9 recorded sales on day 20718 to **$13,499.49 on 11** on day 20719, and a median that steps 4.5 times overnight on two extra sales is not a price we will print beside the eleven steady ones below. Every remaining row has a recorded PSA 9 sale on our tape and none has a recorded PSA 10 sale, and the registry column shows why: the tens exist, but there are so few of them relative to the nines that a ten rarely comes to market and our sold tape has never caught one.

Charizard 103 is the cleanest case. Its registry line holds 3,206 submissions and 49 tens, a 1.5% gem rate, and the market has recorded 37 PSA 9 sales at a $3,500.00 median against not one PSA 10 sale on our tape. A buyer of this card is buying a nine whether they meant to or not. The median PSA 9 across the 403 era cards with one sells for **8.34 times the raw ask**; in Sun & Moon the same figure is 1.58.

"No recorded PSA 10 sale" is not "never sold". It means our graded tape holds no PSA 10 comp for that card, and the tape covers what the provider has snapshotted, not every transaction that has ever happened. The direction of the asymmetry is what matters: 339 one way, 7 the other, on the same tape and the same coverage.

Across the 480 era cards with a trustworthy recorded gem rate on 50 or more submissions, the median rate is **4.4%**. Roughly one submission in twenty-three comes back a ten. The equivalent figure for the Sun & Moon era is 43.1% and for the Japanese promo families 62.9%. Hard to Gem established that the decade decides the gem rate more than the rarity does; this is that finding measured inside one era's full checklist rather than across the catalog.

The easiest card in the era to gem, on the same bar, is Tangrowth from Great Encounters at 37.3%. That is below the Sun & Moon era's MEDIAN. There is no easy end of this era.

The 339-against-7 count is a statement about our snapshotted graded tape, not about every sale ever made, and 1,497 of the 1,941 cards left after the shared-key filter carry no recorded graded sale at any grade. That absence is partly which cards the snapshot cron covers and partly real thinness, and we cannot separate the two. Raw prices are asks and graded prices are sold medians; the 8.34 times figure divides one by the other and inherits both problems. Eight cards are dropped before any graded figure is computed, on the declared bar of 2 recorded sales per graded copy that the methodology sets out, and the bar itself is a judgement: at a bar of 1 the filter would take 16 cards instead of 8, and the headline would read 337 against 4 rather than 339 against 7. Without any filter at all it reads 341 against 11. Glaceon 98 is excluded from the featured tables by a second, narrower rule that applies to one card: its PSA 9 median moved from $3,002.49 on 9 recorded sales on day 20718 to $13,499.49 on 11 on day 20719, a 4.5 times step on two extra sales, and we do not print a median that moved that far overnight. It stays in every count. The two Black Star Promo families of this era are excluded entirely. And no print-run figure exists for any of these sets, so nothing here explains WHY the era gems badly.

Count, over the same twenty sets on any complete day, the cards carrying a PSA 9 sold median with a sample of two or more and no PSA 10 median at the same bar, and the reverse. If the two counts come back within a factor of three of each other, the nines claim is wrong. If the median trustworthy gem rate over cards with 50 or more submissions comes back above 15%, the explanation offered for it is wrong even if the counts hold.

Population: every `cards` row in the twenty English set names listed in the table, 1,949 rows on 2026-09-23, all of them priced. Deduplicating on TCGplayer product id collapses 0 rows in this population. Prices are asks from the daily card tape `price_history` on epoch day 20719, 2026-09-23, a complete day carrying 52,378 priced products; the partial days 20704 to 20713 are not used. Population is PRODUCTS, not catalog rows: one row per TCGplayer product id where present, else the catalog id, ties broken to the lexicographically smallest catalog id. Graded figures are SOLD medians from `graded_snapshots`, latest day per card and grade, read across both the catalog-id and the product-id keyspaces and taking the fresher row, then dropping any surviving median dated before day 20695, the first day of the current daily graded tape, and quoted only where the sample is 2 or more. PSA figures are REGISTRY LINES from `population_snapshots`, latest day per key; many products share one line, so no per-set sum of them is printed. Medians are upper-middle on even samples. The set-value series `sethist2:` is not used anywhere in this study, so a /set/ page's own "Full Set" figure will not match these sums: that is two instruments, not an error. Release dates come from `api_cache` key `report:spread:setsmeta`; the four POP Series sets in this era have no recorded date there and are printed as "not recorded" rather than dated from memory. A card counts as carrying a graded median when its sample at that grade is 2 or more, the same bar the card pages apply, and "no recorded PSA 10 sale" means our tape holds no such comp, never that none exists. SHARED-KEY TEST: A recorded sold count above the registry's own count at a grade is NOT an impossibility: `graded_snapshots` counts SALES and `population_snapshots` counts graded COPIES, and a slab that resells is counted twice on one side and once on the other. What the ratio measures is recorded sales per graded copy, and only a large ratio is evidence that the graded key is pooling another product onto this card. The bar applied here is a DECLARED one, 2 recorded sales per graded copy, not a physical limit. A card is also dropped when two or more sales are recorded at a grade and the registry line records no copies at that grade, because the denominator is then unusable and our feed does not distinguish an absent grade breakdown from a real zero. WHAT THE TEST COULD BE RUN ON: 418 of the 1,949 priced cards carry a PSA 10 or PSA 9 sold median at the two-sale bar and all 418 carry a registry row, so the test is evaluable on every one of them and not evaluable on none. Eight cards fail it here and are removed before any graded figure is computed: over the bar, col1-28 at 3.00 sales per copy, pl2-29 at 3.00, pop6-17 at 10.67 and hgss2-78 at 3.67 on its PSA 9; and with no recorded copies at the graded grade, dp4-15, pl3-44 and hgss2-78 at PSA 10, col1-89 and pl3-SH7 at PSA 9. Every graded count in this study runs over the remaining 1,941 cards while every ask figure runs over all 1,949. A stricter bar of 1 sale per copy would remove 16 instead of 8, adding col1-27, dp6-91, pop6-15, pop8-10, pl3-26, pl3-27, hgss3-5 and hgss2-9, all of which sit between 1.14 and 2.00 sales per copy, a range a resold slab reaches on its own. Gem rates use `gemRateIsTrustworthy()` from @cardapp/core/server and require 50 or more submissions: 480 cards qualify, and an absent rate is excluded rather than counted as zero. EXCLUDED BY WAVE BOUNDARY: DP Black Star Promos and HGSS Black Star Promos, with the other eight English Black Star Promo families, are counted in are Black Star promos worth anything. POP Series 6 to 9 stay in this census as era members; their own study is POP Series Pokemon cards value. The Gold Star cards that sit one series earlier, in POP Series 5 and the EX era, belong to the cheapest Gold Star Pokemon card. The era before this one is covered by EX era Pokemon cards value and its grading by EX era PSA 10 gem rates.
