Collectible coins are numismatic items prized for their historical, aesthetic, or intrinsic value. In the United States, coins like the 1-cent piece (commonly known as the penny) are popular among collectors. Proof sets, such as those issued in 1987, contain specially minted coins with a high-quality finish, struck from polished dies, and are often sought after for their stunning details and limited mintage. Collectors value these sets for both their condition and the unique designs that reflect American history and culture.
