Introduced in 1999, the 50 State Quarters program features unique designs for each US state.
Collectors value quarters based on rarity, mint errors, and condition, known as the grade.
Uncirculated and proof quarters hold higher value than those in circulation.
Special editions like silver proofs can be more valuable, sought after by collectors.
Error coins, such as misprints or double strikes, can fetch high prices on the market.
Some quarters, like the 2004 Wisconsin extra leaf, are famous for their unique errors.
Check for small details that differentiate common from rare quarters, like mint marks.
State quarters with low mintage numbers can be more valuable due to their scarcity.
Preserve your quarters in a cool, dry place to maintain their condition and value.
