Factors Influencing State Quarter Values
Minting Errors
Mistakes such as ‘Extra Leaf’ on the Wisconsin quarter or the use of experimental planchets considerably increase the price of coins by making them rare.
Grade/Condition
Coins are graded on the Sheldon Scale from 1 to 70. Higher grades denote pristine conditions, which are more desirable to collectors.
Rarity
Quarters with limited mintage or unique features are inherently more valuable, as they are harder to find.
Market Demand
Collector interest in specific coins drives up the market value of coins due to enthusiasm combined with historical or aesthetic appeal in some cases concerning certain designs.
Collecting Tips
Authentication: Use professional grading services such as PCGS or NGC if you wish to have your coin certified as genuine and properly graded.
- Proper Storage: Under controlled conditions or in protective boxes to prevent tarnishing and subsequent loss of value; Handle 1999 P.
- Stay Updated: Observe auction results and other people’s opinions on market trends so that you can catch a good opportunity to buy or sell.
- Inspect Your Change: Sometimes, even in the smallest transactions, a valuable coin can slip in- so check those quarters for rare features.
