The 2010 Grand Canyon National Park Quarter was issued as the fourth release of the America the Beautiful Quarters program. Officially, the coins were available through the channels of circulation starting on September 20, 2010.
The new coin represented the Grand Canyon’s second appearance on the twenty five cent denomination in the past three years. The famous site had previously been depicted on the reverse of the Arizona State Quarter issued in 2008. This is one of just a few sites chosen for the present series which were previously depicted on the former series.
The reverse design for the Grand Canyon Quarter depicts a canyon level view of the granaries above Nankoweap Delta, near the Colorado River. The inscriptions surrounding the image read “Arizona”, “Grand Canyon”, “E Pluribus Unum”, and the date “2010”. The reverse was designed and sculpted by Phebe Hemphill. The obverse of the coin features a portrait of George Washington, originally designed by John Flanagan.
The Grand Canyon Quarters will be produced for circulation at the Philadelphia and Denver Mints. The two facilities will also produce satin finish versions of the coin for inclusion in the 2010 Mint Set. The San Francisco Mint will produce proof and silver proof versions of the coin for inclusion in annual sets and special sets issued for the 2010 America the Beautiful Quarters.
