What is the value of a 1958 US quarter?

Updates1958 is not a rare date for Washington quarters. In average circulated condition, its value is determined mostly by the silver it contains. The price of silver changes every day, so check a newspaper or financial site for the current price, then multiply by 0.18 for a rough retail value. A dealer will pay half to 2/3 of that amount. Uncirculated 1958 coins range from $10 to $20 depending on their quality. AnswerValue is wholly dependent on the grade of the coin. A 1958 Washington Quarter, minted in Philadelphia (no mintmark on the coin) has the following value according to listed grade: XF-40 = $2.25; AU-50 = $2.50; MS-60 = $2.75; MS-63 = $3.00; MS-65 = $20.00 and Proof-65 = $6.00. A good beginners guide to grading coins would be The Official American Numismatic Association Grading Standards for United States Coins, 6th Edition, Edited by Kenneth Bressett. There are pictures and descriptions of each coin.
