About Famicom Disk System
Japan-only, the Famicom Disk System (1986) was Nintendo's floppy-disk-based add-on for the Famicom, hosting several games (including the original Legend of Zelda and Metroid) before they were later ported to cartridge internationally. Because it never released outside Japan and its proprietary floppy disks degrade over time, complete, working Famicom Disk System software is a specialized import-collecting niche.
Gamevaro tracks Solomon's Key for Famicom Disk System with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Rarity & condition
Only a handful of market sales have been tracked for Solomon's Key, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Famicom Disk System titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
