Not all United States Mint products come with a Certificate of Authenticity (COA). For example, proof sets contain COAs, but medals typically do not. In some instances, COA language is included in the product packaging.

To ensure that you have a genuine United States Mint Certificate of Authenticity (rather than a replica), look for these two things on your COA:

  1. A signature of a senior official of the United States Mint.

  2. An image of the official U.S. Treasury seal and/or the United States Mint seal.

If you have lost your COA, Contact Customer Service to see if a replacement is still available.

In cases where we have limited-mintage products (e.g., legislatively mandated or Mint established production or mintage limits), the United States Mint may impose order or household limits. Order limits help us ensure that we provide fair purchase opportunities to the broadest audience possible. As we monitor our products, limits may be implemented, adjusted, or removed at our discretion.

Reverse Proof (RP) coin is a coin that features an inverted proof finish. Only the background is frosted, and all other design elements are polished to the same mirror-like finish. An Enhanced Reverse Proof (ERP) has the same frosted background as the RP, but different design finishes. The ERP has multiple polished and frosted finishes assigned to different isolated design elements, where the RP has only a single mirror like polished finish on the design. The selective polishing and frosting of the design elements of the ERP dramatically enhances the visual impact of the design.

Reverse Proof

  • On the obverse, the background is frosted. The entire design and text are polished.
  • On the reverse, the background is frosted. The entire design and text are polished.

Enhanced Reverse Proof

On the obverse, LIBERTY, In God We Trust, the date, sun, sandals, stars, white stripes, and the border, all have a polished finish. The skin, blouse and laurel all have a light finish. The mountains, red stripes, and field on the flag all have a Light+ finish. The ground has a standard level frost.

On the reverse of the coin, all of the text, the stars, the field and outer stripes of the shield, and the border are polished. The Eagle has a light finish. The arrows, laurel, and banner have a Light+ finish. The shield border, and the inner stripes on the shield have a heavy frosting.

The background on both sides of the coin have a heavy frosted finish. All these enhancements— unique to this Enhanced American Eagle Silver Reverse Proof coin—add sharp definition to the designs.
