What is a 2017-S Effigy Mounds Quarter Proof worth?
Age alone gives this coin a small premium, even worn. Sharp details and original surfaces push it higher.
What would make yours worth more:
- Grade and, for proofs, strong cameo contrast
- A die variety or minting error
For market prices, check recent sold results for certified coins in the same grade.
Quick answers

- Where is the mint mark on a 2017 America the Beautiful Quarter?
- On the obverse, to the right of Washington's ribbon. "W" quarters were struck in 2019 and 2020 and released into circulation in small numbers. On this coin the mark is S, for San Francisco.

- 629,997.
What to check on your 2017-S
- Make sure the mint mark really is an S. A worn or filled mark can be misread. It's what separates your coin from the 2017-D (211 million made).
- Judge the grade under good light. Look for luster and freedom from bag marks. "W" quarters in circulation are worth a premium even in average condition.
Proofs from 2017 come with and without frosted devices. Coins with strong contrast are labeled Cameo or Deep Cameo and are worth more.

How to recognize it
The Effigy Mounds design
Iowa's Effigy Mounds National Monument opens the 2017 releases with an aerial view of the Marching Bear Group, a procession of earthen mounds shaped like bears. Native American peoples built more than 200 mounds on the bluffs above the Mississippi River, many of them in the shapes of bears and birds. The monument was established in 1949 to protect them. Richard Masters designed the reverse and Renata Gordon sculpted it.
The America the Beautiful Quarter design
Each reverse shows a national park or other national site, one for every state, the District of Columbia and five territories, with the site's name, its state and E PLURIBUS UNUM. Five designs were issued each year from 2010 to 2020, followed by a final design for the Tuskegee Airmen in 2021. The obverse uses a restored, more detailed version of Flanagan's original Washington portrait.
