$15,000 to spend on 1-5 cards...WWYD?

Here's a somewhat different, and definitely outside the box, take in response to your question. Do some research into sets/issues that PSA does not currently grade, or that they have only started grading very recently so there are only an extremely small number of PSA graded examples from that set/issue out there, so far.

No guarantee you can easily find such an eligible candidate set/issue, if at all. But if you did come across a potential prospect, maybe go after raw cards of the major stars/HOFers in that set/issue, in the nicest condition you can find/afford. Then hopefully you can have them graded by PSA in the future when they do start to grade them, or if they've already started grading them, get PSA to grade them right away while the overall PSA graded pop of such a set/issue is still extremely small. This strategy may be highly time and timing dependent as well, so obviously no guarantees of success.

Certainly not a necessarily easy or predictable thing to do. But then, when has any type of such a riskier investment strategy ever really been that easy or predictable?
