Hello Ransom! NOT worth grading. It's worth probably just around $8- $10. Anytime grading fees are more than the value of the coin then pass on the grading for me anyways.1957 Washington Silver Quarter Coin Value Prices, Photos & Info (usacoinbook.com)
It’s not worth the cost of grading. I’m really tired but from the photos it looks like an impaired proof. It’s silver so that’s a good thing.
