As can be seen
here, Gold's little hiding place for his dagger has been exposed rather unknowingly by Touma.
If your character is the type to be perceptive enough to notice the clues lying hidden about, you have a chance to possibly discover the fact that someone's buried something there.
Admittedly, it is a small one, since if Gold should believe that simply reestablishing the barrier is not an option, he will go dig it up himself and move it to another location; and after he's dug it up til it's been re-hidden, the dagger will remain either on his person or rest warded in his house.
Still, the fact remains that it is currently possible to go snooping around and if observant and intelligent enough about nature, it shouldn't be any problem to find the dig site.
The real factor of challenge I suspect is time, from the moment Gold feels the barrier go down, he's going to be keeping an eye over the area via Gloria, and debating on if he should simply replace the barrier or dig the dagger up and move it.
Thus should he notice too much activity in the area the window of opportunity will begin closing rapidly as he'll have the issue decided by the perceived threat of impending discovery and he'll pop on down there to reclaim it before anyone else can get hold of it.
(Depending on how close people are to claiming it, if he's allowed (ooc-ly) to use magic on the characters, he will abruptly freeze them completely, as in they will freeze and time for them will stop until he undoes the affect after he's finished what he needs to do.)If your character should decide to dig up what is buried, you'll get your hands on one rather special cursed kris dagger.
See the bottom of this entry for what can be done with it should you come into possession of it. Also it should likely be known, that until the man is assured that your character has no intentions of ever using the dagger, anyone who happens to gain possession of it automatically gains negative CR with Gold, that depending on the actions taken while in possession of the dagger
could result in death
(with player permission; elsewise; one could excuse lack of demise as him deciding that due to the lack of permanence of death, it's not worth killing them)If anyone has any questions, feel free to ask!
