The 2025-Mo 1 oz Silver Libertad Reverse Proof in PCGS PR70 with the First Day of Issue (FDI) designation is a highly collectible modern rarity. Below is a detailed description of the coin's design, technical specifications, and the significance of its grading.

Visual & Design Description

* Reverse Finish: This coin features a Reverse Proof finish, which differs from standard proofs. The background (fields) is frosted and matte, while the raised design elements (devices) are polished to a high-gloss, mirror-like shine.

* Reverse (Back): The iconic Winged Victory (Victoria) statue stands in three-quarter relief atop the Independence Victory Column. She holds a laurel wreath of triumph in her right hand and a broken chain of independence in her left. In the background, the legendary volcanoes Popocatépetl and Iztaccíhuatl are visible.

* Inscriptions: 1 ONZA, PLATA PURA, 2025 LEY .999, and the Mo mint mark.

* Obverse (Front): Features the modern National Coat of Arms of Mexico at the center—a golden eagle perching on a cactus while battling a serpent. Surrounding the central seal are 10 historical versions of the coat of arms used throughout Mexico's history.

* Inscription: ESTADOS UNIDOS MEXICANOS.

 Specifications:

* Weight: 1 troy ounce (31.1 grams).

* Composition: .999 fine silver.

* Diameter: 40 mm.

* Mintage: Struck at the Casa de Moneda de México (Mexican Mint) with a limited mintage of 1,500 to 1,900 coins.

Grading & Designation Details

* Grade (PR70): This coin is certified as a "perfect" specimen by the Professional Coin Grading Service (PCGS). It exhibits full original luster with no visible flaws or marks under 5x magnification.

* Deep Cameo (DCAM): High-quality reverse proofs often carry the DCAM designation, noting the intense contrast between the frosted fields and mirrored devices.

* First Day of Issue (FDI): This prestigious pedigree confirms the coin was purchased within 24 hours of its official release and submitted for grading immediately, enhancing its desirability for registry set builders.

Collector Significance

The 2025 series is considered a "black swan" year for the Libertad series. Due to operational challenges at the mint, mintages for many silver versions reached record or near-record lows, and no gold Libertads were minted for the year.
