Drum roll....there were 22 correct entries. I actually ended up finding 4 of these yesterday, so there are going to be TWO winners. Each person was assigned a number and there was a random number generated for the drawing from www.random.org and the winners are Chris(ole 9 ball) and Michelle Dura! Congrats guys and gals. Pm me your address and I'll get them in the mail. Oh yeah...the answers. In 1906 the second building to house the mint survived the devastating earthquake.
Thank you for a fun contest, and congratulations to the winners, if you believe luck comes in streaks maybe you should spend a dollar and buy a lottery ticket before lady luck goes her fickle way.
Thanks for playing everyone. People here really know a lot about searching google...errr, I mean the San Francisco Mint! Congrats again to the winners.
