- Some years and mint marks are rarer than others, affecting their value.

Additionally:

- Look for high-quality details such as sharp outlines and clear legends on the coin's surfaces.

- If you suspect a coin may be fake or altered, it's advisable to seek the opinion of a professional numismatist or coin expert.
