1975 quarters are a part of the Washington Quarter series, minted from 1932 onwards.
No quarters were minted with the 1975 date; they bear '1776-1976' for the Bicentennial.
Special collector's edition in silver clad might fetch higher prices among collectors.
Regular clad quarters from 1975-76 are generally worth their face value: 25 cents.
Coins with errors or in uncirculated condition can be worth more to numismatists.
Look for double die obverses, off-center strikes, or clipped planchets for higher value.
Bicentennial quarters with 'S' mint mark are proofs and are more valuable than regular issues.
Condition is key; pristine, graded coins are sought after and can be worth $100+.
Check for rare varieties, like the 1975 No-S proof, which can be extremely valuable.
Always consult a professional coin appraiser to accurately assess your quarter's worth.
