2019-S Texas San Antonio Missions National Historical Park Quarter GEM PROOF America the Beautiful

San Antonio Missions National Historical Park is a National Historical Park and part of a UNESCO World Heritage Site preserving four of the five Spanish frontier missions in San Antonio, Texas, USA. These outposts were established by Catholic religious orders to spread Christianity among the local natives. These missions formed part of a colonization system that stretched across the Spanish Southwest in the 17th, 18th, and 19th centuries.

In geographic order from north (upstream of the San Antonio River) to south (downstream) the missions are located as follows: Mission Concepción, Mission San Jose, Mission San Juan, and Mission Espada. The Espada Aqueduct, also part of the Park, is due east of Mission San Juan, across the river.

The fifth (and best known) mission in San Antonio, the Alamo, is not part of the Park. It is located upstream from Mission Concepción, in downtown San Antonio, and is owned by the State of Texas. The Alamo was operated by the Daughters of the Republic of Texas until July 2015, when custodianship was turned over to the Texas General Land Office.

On July 5, 2015, the San Antonio Missions National Historical Park, along with the Alamo Mission in San Antonio, was designated a UNESCO World Heritage site.

From 2010 through 2021 the US Mint is issuing commemorative quarters with special reverse designs celebrating National Parks and other National Sites. A park or site is being honored in each of the 50 States, the District of Columbia, and the five US Territories: Puerto Rico, Guam, American Samoa, US Virgin Islands, and Northern Mariana Islands. Each National Park or National Site was selected for its natural or historical significance. The National Park Quarters are being minted and issued at the rate of 5 designs a year, in approximately ten week intervals. The National Park Quarters are being released in the order that the locations were first designated as National Sites. The Obverse side of the coins feature a smaller restoration of the original Washington Quarter portrait, modeled from designer John Flanagan's 1932 plaster. The Reverse of each coin will feature a representation of the unique character and environment of each State, District, or Territory's National Park or Historic Site.

Circulation strikes will be made at the Philadelphia (P) and Denver (D) Mints (starting in 2012 circulation strikes were also minted at the San Francisco (S) Mint). The San Francisco (S) mint will strike the Proofs in clad composition and silver. Clad composition strikes contain an outer layer of 75% copper and 25% nickel bonded to an inner core of pure copper with a 24.33 mm diameter, 5.67 grams weight, and a reeded edge. The silver strikes will contain 90% silver and 10% copper with a 24.33 mm diameter, 6.25 grams weight, and a reeded edge.
