- Summary: The graded vol.1 basket (10 books, each at the grade it trades most, priced at its 28-day median) sits at 80.6 -19.4% vs 90 days ago, -1.9% on the month, +9.0% on the week. Over the month it was pulled down by Dandadan (9.4-9.6, w/obi) (-67.3%) and Kaiju #8 (9.8+, w/obi) (-28.7%), with Frieren (9.4-9.6, w/obi) (+42.3%) and Demon Slayer (8.0-8.5) (+23.9%) going the other way. Bare raw vol.1s are -14.0% on the month (index 56.4), while copies with obi are +26.6% (89.5) the obi market is holding up better than the bare one. The last 7 days had 508 sales for $176,109 -23.3% by count and -28.5% by dollars against the 7 before with 4 of 13 graded series printing higher medians this month than last. On the supply side CBCS completed 1770 slabs in the last four weeks against 1758 the four before (+0.7%) consistent with Beckett Manga Grading Paused: Tankōbon and Zasshi Update. Taken together: flat prices on thinner volume, breadth negative, new-slab supply steady this reads as a consolidation rather than a capitulation while breadth stays mixed; the tell is whether the next two weeks' medians hold the 90-day low, and whether obi and top-tier copies keep decoupling from the bare market.
How to read an index: it is a basket of the most-traded vol.1 books, each valued at its 28-day median sale price, added up and scaled so that 90 days ago = 100. A value of 81 means that same basket now sells for about 19% less than it did 90 days ago; the 1W / 1M / 3M columns are the change over those spans. It measures direction, not the price of any one book.

★ = at least one completed in the last 7 days (Aug 23 Aug 29); "New" = slabs at that grade this month. Est. value = 90-day graded comps for the same book and language (bare copies; zasshi by magazine · year · issue) at the exact grade, else ±0.2, else the nearest grade within 0.6 (≈); "ABOVE any traded grade" means nothing has sold that high yet, so the top traded grade's median is a floor, not a price. Pop at grade = every copy CBCS has ever slabbed at exactly that grade.

Grading volume vs sales
CBCS slabs completed per week (the supply pipe every cert carries its grading date) against graded-manga sales per week across all tracked marketplaces (the demand pipe). Same 26 weeks, oldest → newest; latest week partial.
- Slabs graded/wk · graded sales/wk · sales ÷ new slabs.
- Last 4 full weeks: 1788 slabs graded vs 352 graded sales → 0.20 sales per new slab (prior 4 weeks: 1400 vs 258 → 0.18). Above 1.0 the secondary market is turning over faster than CBCS is adding supply; below it, new slabs are piling up on the shelf.
- Correlation over 25 full weeks, slabs graded vs graded sales: same week r=-0.08, slabs leading by 2 weeks r=-0.15, by 4 weeks r=0.03; slabs vs weekly graded median price r=-0.34. (|r| < 0.3 weak · 0.3-0.6 moderate · > 0.6 strong; a positive lagged r means grading waves show up as sales a few weeks later.)

Reading it: a series where slabs graded outrun sales and the median is falling is being over-graded into a soft bid; slabs scarce, sales steady and median rising is the tight book. Census titles are mapped to tracker names (Kimetsu no Yaiba → Demon Slayer, etc.); zasshi magazines are pooled.
Demand live market
- Active listings: eBay 12,502, Mercari JP 2,221, Yahoo JP 146, Heritage 21. eBay auction share 0%.
- New eBay listings in the last 7 days: 874 (179 graded / 565 raw) vs 841 the week before; eBay sales 231 → absorption 0.26 (prior 0.43, same caveat). 30-day basis (what the sentiment gauge uses): 3752 new listings, 1281 sales → absorption 0.34. Below ~0.35 supply is outrunning demand.
What is on the shelf eBay graded listings by book, days of supply = live copies ÷ (30d eBay sales ÷ 30)
1,680 slabs live across 884 distinct books (30d eBay sales covered 299 distinct books). By series: One Piece 676 (40%), Dragon Ball 157 (9%), Berserk 108 (6%), Jujutsu Kaisen 108 (6%), Naruto 89 (5%), Demon Slayer 77 (5%), Bleach 55 (3%), Dandadan 50 (3%). Variety is wide on paper, but depth is concentrated: a book with 40 copies live and 3 sales a month is 400 days of supply.

What to watch
- Beckett Manga Grading Paused: Tankōbon and Zasshi Update if grading intake stays closed, expect thinner new-slab supply in 4-8 weeks (velocity is the tell); raw 1st-print demand may firm as collectors hold books to slab later.
- Graded index 1W (+9.0%) and 1M (-1.9%) disagree a turn, or noise from a thin week; wait for a second week before re-pricing.
- 12 new highs printed (Dragon Ball Vol.1 slab 7.0 JA, Fist of the North Star Weekly Shōnen Jump 1983 Issue #41, One Piece Vol.61 slab 9.8 w/obi JA) check whether they were auction results (one bidder) or fixed-price (market-wide).
- 134 auction lots (est. $855,019) close soon Heritage/Goldin results reset the top-tier comps for the books involved.
Long-term health the whole record
Record: sales from Oct 2020 to Aug 29, 2026 (27,088 sales 5,939 graded, 16,937 raw, 4,152 zasshi); CBCS completions from 2023-09 (23,026 certs). The 90-day indices above are re-based here over the whole record so peaks and drawdowns are visible.
Long-run indices (base 100 at the start of each record; constituents = books with ≥12 sales over the record)
| Index | Now | All-time high | vs high | 12M |
|---|---|---|---|---|
| Graded JP Vol.1 | 469.3 | 771.4 (Apr 2026) | -39.2% | +359.9% |
| Raw JP Vol.1 (Mercari+Yahoo) | 221.0 | 426.0 (Jun 2026) | -48.1% | +130.4% |
| Raw JP Vol.1 w/Obi (Mercari+Yahoo) | 267.1 | 328.7 (Jun 2026) | -18.7% | +169.3% |
| Zasshi First Appearances | 272.0 | 369.7 (Jun 2026) | -26.4% | +141.7% |
Each record starts at its first month with 20+ sales; the early stretch is thin (a handful of sales per book per month, values carried forward between them), so read the first year as shape, not level.

Health read (rule-based, whole record)
- Graded JP vol.1: index 469.3 -39.2% from its all-time high (771.4, 2026-04) and +405.7% above its low (92.8, 2025-07); 12-month change +359.9%.
- Raw JP vol.1 (bare): index 221.0 -48.1% from its high (2026-06), +179.3% above its low (2026-02).
- Volume: last full month 2,256 sales / $934,218 vs the same month a year ago 309 / $82,162 (+630.1% by count, +1037.0% by $); trailing-12-month sales 19,400 vs the prior 12 months 3,622 (+435.6%).
- Supply: CBCS completed 1,759 slabs in the last full month vs 324 a year earlier (+442.9%); graded sales per new slab 0.16 now vs 0.46 then (above 1 = the market absorbs more than the grader adds).
- Coverage caveat: the tracker recorded sales across 90 series / 4 marketplaces last month vs 57 / 2 a year earlier most of the volume growth above is the tracker widening its net, not demand; use per-book medians, the indices, and sales-per-slab for like-for-like history.
- Of the 11 most-traded graded series, 1 trade at less than half their peak-month median (Jujutsu Kaisen) and 3 within 10% of it (Frieren, Kaiju #8, Dandadan).
Prices are public sales across eBay, Mercari JP, Yahoo! Auctions JP, Heritage and Goldin, collected by West Blue; indices are baskets of the most-traded vol.1 books at their 28-day median, scaled to 100 at 90 days ago. Obi and bare copies are never blended. This is market commentary, not investment advice.
