Why Are These Quarters So Special?
The value of these quarters lies in their scarcity and errors. Minting anomalies, such as doubling, cracks, or extra design elements, make them stand out from standard coins. Additionally, their uniqueness appeals to collectors who are willing to pay significant amounts for rare finds.
For instance, the valuable state quarters like the Wisconsin “Extra Leaf” or Delaware “Spitting Horse” become even rarer as they remain undiscovered in circulation. As a result, their worth continues to climb.
