Lots of old things are scarce. Arcade games are in the same boat, but you've got MAME and I've got a bit-slice coprocessor and rasterizer ASIC controlled by a 6809 in I,Robot.

The main difference is that creating a 100% perfect copy of a game costs next to nothing, and creating a new 100% perfect copy of model T is almost impossible, even if you have one to copy it from.
