Well, perhaps I'm jaded from thirteen years of life with one of these kids without any apparent levers... but at least at my house, I'd not assume that this was because I'd found her currency. Though, to be fair, I used to think that.

I'd be so hopeful when I would try something and it would.... WORK!!! (Hurray, right? Meh... not so much, actually.)

Rather, I'd probably chalk it up to "oooooo--- SHINY" since pretty much ANY new strategy that we try works. At least once, I mean-- but generally no more than three times. Almost all keys seem to be single-use with this particular child.
