The 1986 quarter is part of the Washington series, minted from 1932 onwards.
Most 1986 quarters are worth face value, but mint condition coins can fetch more.
Special mint sets or error coins from 1986 may be highly valuable to collectors.
Check for a 'S' mint mark, indicating a proof coin from the San Francisco Mint.
Proof coins have a mirror-like finish and are sought after for their aesthetic appeal.
Uncirculated and proof 1986 quarters can be worth $1 to $5 or more.
Graded coins by services like PCGS or NGC can significantly increase in value.
Rare error coins, like off-center strikes, can be worth hundreds of dollars.
Always consult a professional coin appraiser to accurately assess your quarter's worth.
