How it works
RetroQuote is not a price guide written by experts. It is a record of what people actually paid, built with a simple and strict method.
Only concluded auctions
Every figure on this site is the final bid of a public online auction that closed with a sale. We do not record asking prices, "buy it now" sales, private deals or dealer listings: an asking price tells you what the seller hoped for, a closed auction tells you what a buyer was willing to pay.
Whole machines, one at a time
We record single machines and consoles. Bundles of several machines, lots of games or accessories, and spare parts such as motherboards or keyboards are left out, because their price cannot be attributed to one model. A machine sold with its own power supply, cables or a few tapes is fine.
Five conditions, plus the box
Each sale is filed under one of five conditions, as described by the seller and checked against the photos:
- New old stock: never used, often still sealed.
- Working, good condition: tested and working, clean.
- Working, poor condition: works, but yellowed, scratched, missing keys or badly worn.
- Not working or untested: declared faulty, or sold without testing.
- Unknown condition: the listing did not say.
We also note whether the original manufacturer's box was included, since it changes the price a lot. Any other box does not count.
Euro, at the exchange rate of the day
Sales in other currencies are converted to euro at the European Central Bank reference rate of the closing day, and rounded to the whole euro. Shipping costs are never included.
Found by software, confirmed by people
Auctions are collected from the main online marketplaces by our own software, which reads each closed listing, converts the price and proposes a model and a condition. Nothing is published automatically: a member of the association reviews every proposal, corrects it where needed, and only then the sale appears on the site. Proposals that cannot be verified are discarded.
What the numbers mean
For each model we show the average of the recorded sales, by condition, together with the number of sales and the lowest and highest price. Averages of few sales move a lot from one year to the next: always look at how many sales stand behind a figure. The chart shows every single sale, so you can judge for yourself.
Where the data comes from
The archive started in 2014 with sales recorded by hand by volunteers of ESOCOP. Since 2026 it is fed by our collection software, reviewed as described above. We do not publish links to the original listings, nor the sellers' photos.
