Amounts Printed and Populations
The state that had the least amount of quarters produced was Oklahoma, with only 416,600,000, according to U.S. Coin Value Advisors. Other states with minted amounts under 500,000,000 include Minnesota, Illinois, Alabama, Maine, Missouri, Arkansas, Michigan, Florida, Iowa, Wisconsin and New Mexico. In some cases high-populated states such as Illinois and California had relatively small numbers of coins based on the state populations. These coins may be slightly more difficult to find than states such as North Dakota and South Dakota, which have smaller populations.
San Francisco Mint
Almost all of the state quarters were minted in either the Denver or Philadelphia mint. A small portion of quarters were minted at the San Francisco mint. These quarters were struck twice and were designed to be proof sets. San Francisco state quarters were not released for circulation. To determine if a quarter was struck in the San Francisco mint look for the letter "S" under the "In God We Trust."
Wisconsin Error
With literally billions of quarters printed, there will be errors that occur. The Wisconsin error quarters are have an additional leaf on the ear of corn displayed on the coin. The error occurs in two fashions, one with the extra leaf being vertical and the other with the extra leaf being on the horizontal. Keep a keen eye, the error is not obvious, as the leaf does not look out of place.
Other Errors
Other errors are common through a number of state quarters. These errors include missing design features. On these coins the die does not strike the coin clean, resulting in blurred images or letters being left off the coin. Another error is having one side of the quarter being copper in color rather than the silver. Also off center strikings of the state logos is not uncommon. Error coins can be difficult to locate, as they are quickly picked up by collectors.
