Description
90% Modern Proof Strikes are a type of coin strike that combines the brilliant mirror-like fields of a traditional proof coin with the frosted, sculpted devices found on uncirculated coins. This striking technique, introduced by the United States Mint in the early 2000s, aims to create a visually appealing contrast between the highly polished background and the textured design elements. The "90% Modern" designation refers to the fact that these coins contain 90% silver, similar to the classic silver coins minted before 1965. These proof strikes are highly sought after by collectors for their unique appearance and limited mintages, offering a modern twist on traditional numismatic artistry.
