I may be wrong on this, but I'm pretty sure on your dollars the one from san francisco is a proof. I think that the san francisco mint only mints proof coins these days...
Well, I think you just learned that coins tone differently and that's because of a variety of factors. :hail:
It could be that the presses used, are set much higher with tonnage for the dies, this could cause this condition and the difference from all mints. -O) This can be, whether they are UNC or PROOF coins
Proof coins (now made in SF) are coins made specifically for collectors on specially prepared dies and specially prepared coin planchets so that when they are produced they have a mirrored backgrond and frosty devices. In other words, they look a lot shinyer than the regular P and D mint examples.
To add to the clarification already mentioned, for the benefit of the new collector/OP, as to where Proof coins are currently struck, certain other Proof coins are struck at West Point with a "W" mint mark, such as: the American Gold Buffalo, First Spouse Gold coins, Platinum Eagle coins and the AGE and ASE coins (but not this year for the later.) And while not necessarily "proof" the 2009 UHR coins are struck at West Point. Some UHRs have been graded "proof-like", but I haven't come across any TPGs employing the "shiny" designation just yet.
