I don't recall seeing a reusable
Identify item in print, but I don't have a number of the recent books.
The cost would depend on who made the item in question.
If an arcane caster made it it would cost:
1,800gp (command word item)
x1 (1st level caster)
x1 (1st level spell)
+5,000gp (50x 100gp material cost)
=6,800 gp for 5 uses per day
/5 (1 charge per day)= 1,360gp to purchase (680 gp and 54 XP to make with Craft Wondrous Item)
If you wanted 3/day version, it would cost 4,080gp (2040gp and 163 XP to make with Craft Wondrous Item).
A Cloistered Cleric (Clerc variant in Unearthed Arcana or the SRD) could make it for
1,800gp
x1 (1st level caster)
x1 (1st level spell)
+0gp (no material component for divine casters)
=1,800gp for 5 uses per day
/5 (1 charge per day) = 360gp to purchase (180 gp and 14 XP to make with Craft Wondrous Item).
3 charges per day would cost 1,080gp (540 gp and 43 XP to make with Craft Wondrous Item)
Keep in mind, both version are at caster level 1, so that will affect interactions with effects that conceal or distort magic, such as
Nystul's Magic Aura.
