Those are nice coins. It pains us collectors when someone call an old silver coin 'scrap.' But, alas, you are right. Both coins are very common and not worth much more than base silver value.
Washington quarter: 0.181 troy ounces silver
Peace dollar: 0.773 troy ounces silver
At today's silver price of about $22 US dollars per troy ounce, that's about
Washington quarter: $4 base value
Peace dollar: $17
You can sell them at these prices or, perhaps, you can give them to a young person who might be interested in coin collecting.
Thanks for writing.
