Nami Moved Up Fast. September Ended Differently.
Copies kept changing hands as this exact English foil moved higher. The last week in the record was noticeably quieter.
For someone following Nami from Extra Booster: Anime 25th Collection, late summer brought a clear change. This exact English Near Mint Foil printing rose from $15.03 on August 31 to $19.34 on September 28—a 28.68% increase.
This was not one lonely price sitting on a chart. Copies kept changing hands along the way. Then September ended with a very different week: the card did not stop moving, but the latest reading was noticeably quieter.
This was more than one price
Across the latest four retained weeks, there were 394 tracked transactions and 925 units. Across the prior four, there were 378 tracked transactions and 887 units. Those totals sit close together, which is the useful part: copies kept changing hands as this printing moved higher.
Transactions count sales records; units count the cards in them. One transaction can include more than one card, and neither count tells us how many individual collectors were involved.
Recent activity
Copies kept moving through the rise. The newest week was quieter.
Transactions and units are shown separately across eight retained weekly points, with the September 28 change called out.
Then September ended quietly
From September 21 to September 28, tracked transactions fell from 122 to 66, units fell from 282 to 147, and price eased from $20.15 to $19.34.
The difference is easy to see without turning it into a forecast. Nami had been busy through the rise; by September 28, it was not moving at the same clip. That quieter finish is the part to keep beside the bigger four-week picture.
How to read this printing now
The verdict is SIGNAL. That is not an investment rating or a promise about what comes next. It means the late-summer rise had real recorded activity behind it, and the newest week was much quieter.
A collector following this card now has a useful before and after: several busy weeks carried Nami as high as $20.15, followed by a week with roughly half as many recorded sales and copies. The change in rhythm—not an invented reason for it—is what this dated record adds.
What to watch next
One quiet week can stand out. Once four more weeks are available, the useful question is whether copies start changing hands more often again or the late-September quiet continues.
If both recorded sales and copies keep falling while price also moves below the August 31 starting point, this read no longer holds. The exact comparison is preserved below in Sources & Data.
Method
Sources & Data
The evidence attached to this Feature, kept separate from interpretation.
- Exact card
- Nami · Extra Booster: Anime 25th Collection · English Near Mint Foil · product 629110
- Evidence dates
- Captured October 2, 2026. Latest retained weekly bucket: September 28, 2026. This is dated evidence, not a live October 8 market reading.
- Price comparison
- $15.03 on August 31 to $19.34 on September 28 (+28.68%). The September 21 retained price was $20.15.
- Activity counts
- Latest four retained weekly buckets: 394 tracked transactions / 925 units. Prior four: 378 / 887. Newest bucket: 66 transactions / 147 units, down from 122 / 282 one week earlier.
- What would change the read
- After another complete four-bucket window, the verdict fails if both totals fall below 378 tracked transactions and 887 units while retained price also falls below the August 31 reference of $15.03. A material correction to card identity or the retained series also voids the read.
- Limits
- Transactions count retained sales records, not unique buyers. Units and transactions are distinct. The dataset does not establish demand, scarcity, liquidity, intent, causality, investment merit, or future direction.
Takeaway
This Nami did not reach $19 on one lonely price. Copies were moving through the rise; the much quieter final week is what changes the story.
