Top 25 most expensive WS games by loose market value — prices from real eBay sales
Bandai's WonderSwan (1999) was a Japan-only handheld designed with input from Nintendo Game Boy creator Gunpei Yokoi's team, and it built a respectable library before being succeeded by the color version. Since it never released outside Japan, WonderSwan collecting is entirely an import hobby internationally, with complete, boxed copies especially prized by handheld collectors.
This list shows the most valuable WonderSwan games based on current loose market prices sourced from eBay. Values are updated regularly and reflect real collector transactions. CIB (Complete in Box) values are typically 2–5× higher than loose prices.
Ranking by loose price surfaces a different set of standout titles than ranking by collector demand — a game can be genuinely valuable on the resale market without being widely collected, or the other way around, especially on a smaller-library platform like WS where a handful of scarce releases can dominate the top of the value chart.
