Many people may not be aware of the rarity and value of these particular coins. They might mistake them for regular dimes and quarters, leading them to remain in circulation unnoticed.
Dimes and quarters are among the most commonly used coins in everyday transactions. They are frequently exchanged and passed around, increasing the chances of rare ones staying in circulation.
Some individuals who come across these rare coins might not be serious numismatists or collectors. They may unknowingly spend or use them in transactions instead of safeguarding them.
Sometimes, rare coins enter circulation due to minting errors. These errors might not be immediately recognized, allowing them to be spent like regular coins.
Without proper authentication, people might not realize the true value of these coins. They may assume they are regular coins and use them for everyday purchases.
Even if individuals are aware of the rarity of these coins, they might choose to keep them in circulation due to sentimental attachment or simply not realizing the potential windfall they could receive by selling them.
The longer rare coins remain in circulation, the harder it becomes to track them down. They might change hands multiple times, further obscuring their origins.
