I think its a perfect comparison. Both ASM300 & Spiderman 1 were known books that came out in the late 80/90. The chromium editions came out 10/12 years after they were well established/quite collectible. Tec880 seems to be selling for 50, and as @ygogolak mentioned, its close to what the retailer was asking for cover.
Im not suggesting it would fetch 10 times the price in the future, that remains to be seen, mainly depending on demand for the book and future reproduction of said variant.
But based on current demand and low print run of 1,000, I can see how it could get to those levels
