The 1883 Liberty Head Nickel in MS 66 No Cents is a highly sought-after coin in excellent condition. Here’s a breakdown of what each part of the description refers to:

The 1883 Liberty Head Nickel is part of the series that ran from 1883 to 1912, with the design featuring Lady Liberty on the obverse. The reverse shows a large "V" for "five cents." This particular year is notable for the absence of the "CENTS" inscription on the reverse of some early issues, which is why it is often referred to as the No Cents variety. The issue without the "CENTS" marking led to some confusion, as the coin looked very similar in size and appearance to a gold piece, leading to some people mistakenly trying to spend it as a $5 gold coin.

The MS 66 grade means the coin is in near-perfect condition, showing only a few very minor imperfections visible under magnification. Coins in this grade are well-struck, with outstanding detail and minimal surface marks, making it a top-quality example for collectors of the Liberty Head Nickel series.

The CACG is likely a typo for CAC (Certified Acceptance Corporation), which is an independent organization that reviews coins graded by major certification agencies like PCGS or NGC. If the coin has received a CAC sticker, it means it has passed an additional layer of quality review and meets a higher standard of preservation than other MS 66 coins, making it even more desirable.

In summary, the 1883 Liberty Head Nickel MS 66 No Cents with a CAC sticker is a high-quality, collectible coin, and the "No Cents" variety adds to its appeal and rarity.
