The 1-5/16"-diameter medallion is connected to the 1-1/4"-diameter key ring with a 5-link chain.   

The front of the medallion says "The 150th Anniversary of the McCormick Reaper  1831-1981."  The back says "WE HARVEST IDEAS" below the IH logo in the center.  

Includes the plastic bag it originally came in, but the bag was slit to remove the item for photographing.   

I believe this was "Made in the USA" but there is nothing on the item or bag telling the Country of Origin.  1981 would have been very pre-made-in-China.
