Are they specific spells it casts every time? Or does it "hold" spells in the manner of a Ring of Spell Storing?
If it's the former, we're probably talking about a command word triggered item. In that case, it'd follow something like this.
Spell Level x Caster Level x (Uses per day/5) x 1800 gold.
But you add 50% extra if it's an additional effect. So for a level 1 spell it'd be:
1 x 1 x 1/5 x 1800 x 150% = 540 gold
If you're crafting it yourself, it'd be half that.
