2019-S San Antonio Missions Proof

San Francisco struck the 2019-S San Antonio Missions clad proof at 942,693 pieces, the figure matching the U.S. Mint Clad Proof Set sales total because the five 2019 quarters shipped as a packaged product. Chris Costello's reverse honors the bell tower and ornate facade of Mission San Jose, the largest of the five Spanish colonial missions preserved within the San Antonio Missions National Historical Park in Texas. The composition reaches back to 1720, when Franciscan friars founded the mission, and renders the carved limestone in the kind of detail the design's relief can carry at quarter scale. The issue is the fourth of five 2019 releases and the 49th of the 56-design ATB program.

Proof finish on the issue is the standard San Francisco style: mirrored fields struck from polished planchets against dies frosted in chemical baths before each press run. Cameo (CAM) and Deep Cameo (DCAM) are the contrast designations PCGS, the Professional Coin Grading Service, and NGC, the Numismatic Guaranty Company, apply on top of the numeric grade, with DCAM the default outcome rather than an upgrade tier. The bell tower's carved facade and the recessed window detail are the diagnostic strike areas, with die wear softening the carved relief first because the architectural detail concentrates in the design's middle relief plane. Grade distribution clusters at PR69-DCAM and PR70-DCAM with top-tier population counts in the thousands. The clad composition (75% copper-nickel over a pure copper core, 5.67 grams, 24.26 mm) matches every Washington quarter struck since 1965, so counterfeit risk is essentially nil at the issue's price point.

The issue routes through year-set or design-set assembly. A raw certified PR69-DCAM example moves for a small premium over the cost of breaking up a sealed 2019 Clad Proof Set, and PR70-DCAM examples in NGC or PCGS holders sit at a modestly higher tier. The dense architectural relief of the Mission San Jose composition makes it one of the more grading-sensitive designs in the year's proof group, which gives the issue slightly firmer top-grade interest at PR70-DCAM. The Semi-Key 2019-W catalogmate absorbs the bulk of premium-end attention for the design, leaving the clad proof priced through the entry-level proof market.
