GameStop has listed a Doom Floppy Disk Limited Edition Imitation Gold Plated Replica at $29.99. Let’s unpick that for a moment. These are imitation floppy disks coated in imitation gold, delivered in a commemorative box. There’s a display stand included, too. However, these are non-functioning 'floppy disks' inspired by the Doom v1.2 shareware release and don’t contain any game data. Doom's single-level ‘Knee‑Deep in the Dead’ shareware release is still free to download, though, as it has been for many years.
