The San Francisco Mint has been minting quarters since 1855 except for a few years in the 1880's, the 1950's and 1960's. In all of that time it would be safe to say the "S" mint coins are, generally speaking, less common than those of the Philadelphia and Denver mints but to say "how rare" is difficult. Of course, rarity is not always equated with mintages but more often with how many of those coins minted still exist. The lowest mintage was in 1866 when the were 28,000 "S" mint quarters struck and the highest mintage was in 1943 when there were 21,700,000 "S" mint quarters struck. The bottom line is that rarity is a term used to describe something that is not commonly found.
Minted in San Francisco
If well-worn, about $6 regardless of mint mark. If almost uncirculated, 1940 quarters from Philadelphia are worth around $10, S-mint (San Francisco) coins go for about $15, and D-mint (Denver) coins are about $30.
It simply means the quarter was minted in San Francisco. San Francisco minted quarters for circulation from the 19th century up to 1954. These coins have a small S on the back under the eagle. In 1968 proof coin production was transferred from Philadelphia to San Francisco so proof coins made since then carry the S mint mark. New proof quarters have the mint mark to the right of the bow in Washington's wig. San Francisco often made fewer coins than Philadelphia or Denver so coins with that mint mark MAY (but not always) be worth a bit more than those from the other mints. For most common date Washington quarters up to 1954, however, the price of silver is now high enough that those coins are worth more for their silver content than as collectibles unless they're in almost-new or uncirculated condition.

You can determine if a 1896 barber quarter is from New Orleans or San Francisco by looking at the mint mark located on the reverse side below the eagle's tail feathers. If it has an "O" mint mark, it was minted in New Orleans. If it has an "S" mint mark, it was minted in San Francisco.
The 1861 Quarter Eagle was struck at the Philadelphia Mint and the San Francisco Mint.

Look at the coin again, the San Francisco Mint did not strike any quarters in 1934.
The US Mint did not issue any coins from the San Francisco mint for circulation purposes. That said, it is possible that someone spent a proof Minnesota quarter (which would have an "S" mintmark but intended for collectors rather than commerce), and thus put it into circulation.
The letters "S" and "D" on a bicentennial quarter indicate the mint where the coin was produced. "S" represents the San Francisco Mint and "D" represents the Denver Mint.
All Washington quarters dated 1932 to 1964 had the mint mark on the back under the bow of the wreath. No mint mark = Philadelphia D = Denver S = San Francisco (up to 1954)
1919 makes it a Standing Liberty quarter, so the mint mark is on the obverse (heads) side, just to the left of Liberty's feet. D is Denver, S is San Francisco, and no mark is Philadelphia.
