I picked this up because it was cheap and neat. Weighs 5.5g, strangely. The buffalo reverse appears to have added/enhanced details and wierdly containing an added 1812 date where FIVE CENTS was. And the obverse converted to a medal alignment with what looks was a work-in-progress Korean War remembrance of some type. Buffalo side and the smooth rim have that brassy look. I couldn’t make out any remnants of the original obverse. Please share any thoughts about this you may have.
It's actually a Korean War medal. https://www.collectorsweekly.com/stories/212009-17th-infantry-regiment-challenge-coin-19
