Generally speaking, drilled holes can detract from the aesthetic appeal and historical significance of a coin, making it less valuable to collectors and investors. The hole may have been created for various reasons, such as using the coin as a piece of jewelry or attaching it to a chain. However, such modifications can diminish the coin's numismatic value.
It's important to note that the specific value of a coin with a hole can vary depending on market conditions and the opinions of individual buyers or sellers. Some collectors may still find value in such coins, especially if they are rare or have other desirable characteristics. However, it's generally recommended to avoid purchasing coins with significant damage, such as holes, as they can impact the coin's overall value and authenticity.
