1927-S Full Head Standing Liberty Quarter Sold at auction: $175,000 Bottom line: With only 396,000 produced, the 1927-S had the lowest mintage of the Standing Liberty quarters.
It is estimated that about 3,900 of these were Full Heads. Today, 65 Full Heads are known, but only two are finer than this one, which is why it's a valued collector's item.
1919-S Full Head Standing Liberty Quarter Sold at auction: $235,000 Bottom line: While 1,836,000 quarters were produced in San Francisco in 1919, the date on many of these has worn off.
Very few remain in mint condition, and only three others are of equal quality to this one.
1901-S Barber Quarter Sold at auction: $258,500 Bottom line: The San Francisco Mint produced 72,664 quarters in 1901, and most of them were placed in circulation.
With regional circulation heavy in the West, very few of these coins survive in mint condition, with only two certified mint by PCGS and two Superb Gems by NGC.
These coins were gradually rolled out, with dimes and quarters first appearing in 1796. Because of low demand, quarters were not produced again until 1804.
