Three factors that influence the purchase price

rarity
The "number in existence" is important, not the number of copies issued. Even if tens of thousands of copies are issued, if there are only a few hundred copies in existence, they will be expensive.
Grade (Condition)
Evaluated by the degree of surface wear, scratches, and dullness. If it is in good condition, the assessed value can be several times higher.
Popularity and collectability
Historical value, design aesthetics, and collectors' attention are directly related to value.
