What is the value of a 1959 US quarter?

Answer 1

1959 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.

A nice uncirculated one can sell for around $10, with the possibility of going as high as $700 for a top-quality strike.
