it could simply be that you value owning the object in terms other than money. sentimental reasons, completionism tendencies, novelty, some other "non-rational"/emotional reason; any of these can have a stronger pull on the mind than $1300 to someone who doesn't immediately need the cash for survival. i have some records like this (not in that price-range but still) along with a few other collectible items (some rare handmade keycaps that were going for over $500 a piece at one point) that I refuse to part with for money because i just... like them :)
