Antminer Z9 Mini resale value: the numbers
| Window | Sales (n) | Median | Middle half | Low to high |
|---|---|---|---|---|
| Last 30 days | 7 | $225 | $176 to $285 | $80 to $335 |
| Last 90 days | 14 | $126 | $77 to $219 | $20 to $335 |
| Previous 90 days | 17 | $85 | $65 to $225 | $36 to $777 |
Every window covers machines sold as pre-owned. First, we remove price outliers. Then we take medians, because one odd sale can wreck an average. Per kSol/s that works out to about $12.62. Shipping is not in these prices. When the buyer paid it, the median charge was $20, and 21% of sales shipped free.
What is driving the Antminer Z9 Mini price
The 30-day median is up 181% on the window before it. That looks like a real move, not noise. Still, it rests on a modest number of sales, so treat the size as approximate. However, we cannot see why each buyer paid what they paid. Instead, we see the price that cleared. In general, rising used prices mean buyers expect better mining margins or supply has thinned.
How it compares with the Antminer Z15
The nearest model on the price ladder is the Antminer Z15. It has a 90-day median of $4,874 on 20 sales. So the Antminer Z9 Mini sells for 95% less. In short, that gap is wide, so the two are not close substitutes.

Buying or selling an Antminer Z9 Mini
Use these numbers as a check on any quote. First, if you want to sell, start on our we buy used miners page. It takes a description and gives you an offer. Next, try the free What is my miner worth? tool. To buy instead, see the Antminer Z range or browse all used ASIC miners. Also, every model we track appears on the used ASIC miner prices by model page, and the full table is in the ING Used ASIC Miner Price Index.
How we count these sales
Every figure comes from completed eBay sales that our collector recorded up to October 30, 2026. We keep US-dollar sales of single working machines only. We drop parts, lots, repair listings and sales with no model in the title. Then we remove price outliers. Also, we publish a cell only when 5 or more sales stand behind it. The price is the item price, with shipping left out. For the full rules, read the index methodology. Bitcoin network data for the mining maths comes from mempool.space.
In short, our take is to trust the sold price, not the asking price. For the Antminer Z9 Mini that means $225, give or take the $176 to $285 band.
