1926 Oregon Trail Commemorative - What Do You Think? (PCGS)

Though the relief on the Oregon Trail half dollar is better than on some other commemorative coins (e.g., the Monroe Doctrine Centennial half dollar), it was not struck in true "high relief."

On the coin shown here, there is quite a bit of toning framing the raised devices. These darker outlines do give the impression of a higher/deeper relief than what is actually present. That's part of what makes the visual aesthetics of the coin so impactful.
