Can I change where my coin's QR code points after the coins are made?

Not the code itself — once the mold is cut, that pattern is permanent. What you can change is the destination, as long as you plan for it up front.

Point the code at a short link or a redirect you control rather than at the final page directly. The coins keep pointing at the same address forever, and you repoint that address whenever you like: a contest entry form this year, a results page the next. Organizations running multi-year coin programs almost always do it this way.
