Here are some factors that can affect the value of a Canada one cent 1919 coin:
* Condition: The condition of a coin is one of the most important factors in determining its value. Coins that are in good condition, with few or no scratches or blemishes, are worth more than coins that are in poor condition.
* Rarity: The rarity of a coin also plays a role in its value. Coins that are rare are worth more than coins that are common. The Canada one cent 1919 coin is not particularly rare, but some varieties of the coin are rarer than others.
* Grade: Coins that have been graded by a professional coin grading service are worth more than coins that have not been graded. Grading services assign a grade to a coin based on its condition, rarity, and other factors.
