That's how much Richard Garriott (son of astronaut Owen Garriott, creator of the Ultima game series, and after that, private astronaut that spent 12 days at the ISS) spent to purchase the rights to Lunokhod 2 and the Luna 21 lander.
If it had been launched fast enough it could have become the first American (self-driving) rover on the moon. And still among the first ten rovers. That would be worth something to some collector
owning a passive lunar rover will surely give you some publicity and access to something (you can brag about it in some venues). People have successfully monetized more stupid things. I'm not saying _I_ would know how to get returns from that investment but I'm sure there are some people who would.
