Jaime Hernandez: In 2010 the Mint struck two versions of the 5 Ounce America the Beautiful Quarters, which are the Bullion version and the Collector version.
The Bullion version (no mint mark) was only sold to Mint Authorized Bullion Purchasers. These Bullion Purchasers then resold the coins to the public. The Collector version (Special Strikes) will have the P mint mark and also have a slightly different finish created by a special vapor blast techique compared to the crilliant finish seen on the Bullion versions.
