Postal Numismatic Covers (PNCs) are collectible items that combine two main elements:

1. A commemorative coin or medal (numismatic item)

2. A specially designed envelope (cover) featuring postage stamps and postmarks (postal element)

These covers are often issued to mark significant events, anniversaries, or notable figures, and are usually produced in limited editions. They are popular among both stamp collectors (philatelists) and coin collectors (numismatists).

Key Features:

• Coin or Token: Often inserted into or affixed to the cover.

• Postage Stamp(s): Usually relevant to the theme, and typically canceled with a special postmark tied to the event or date.

• Envelope Design: The artwork complements the theme (e.g., royal events, historic milestones, space missions).

• Limited Editions: Often numbered and sometimes accompanied by a certificate of authenticity.

Example:

A Postal Numismatic Cover commemorating the 50th anniversary of the Moon Landing might include:

• A special lunar-themed coin

• A stamp featuring the Apollo 11 mission

• A cancellation mark dated July 20, 2019 (the anniversary date)

• Illustrative envelope artwork showing astronauts or the lunar module

They are primarily collectibles and usually hold sentimental or collector's value rather than high monetary value unless rare or in demand.
