Recently found one of these in the Medallic Arts ivory box. Ba-Haw Arapahoe. Much different box than the old original green box with gold print. This more modern issue has a filled in reverse creating a solid blank back medal rather than the hollowed out back found on originals. There is an edge seam visible where this joining took place. Lighter in color similar to modern issues. Same 71mm size. Nothing to indicate date of issue.

I also have a few of these. Mine are still in the orinial issue boxes. They also are lighter in color than the collection shown above. I would guess that would have something to do with how they were stored & also the climate they were exposed to. Depending on your location, you might try viewing examples that are housed in several museums around the nation and compere. I am not aware of any of these being re-made or of counterfiets showing up in the marketplace.
