+14 climbing enhansive

[Markx]

What'd the going rate be on something like this? Thanks.

ivory-inlaid star sapphire pin
It is a magical item which could be imbedded with a spell.
It does not have any charges left.
It is rechargeable.
It could be activated by waving it.
It provides a boost of 14 to Climbing Bonus.
This enhancement may not be used by adventurers who have not trained 35 times.
The pin looks to have a lot of charges remaining.
It will crumble into dust after its last enhancive charge has been expended.
It will disintegrate after its last magical charge has been expended.
It is a small item, under a pound.

Most (all?) climbing checks seem to look at ranks, so I'd imagine it's not as valuable as it could be. I wouldn't think it'd have much value.... but there's always that one person that seems to want enhansives with big numbers....
