Can any of you medal guys tell me anything about this? It's in an upcoming auction I may be attending, and it piqued my interest. Trying to figure out if it's authentic or a modern repo, and approx value (if any). I have found info on similar medals, but not with the same obverse and reverse. Description says - Total weight approx. 76 grams. Measures 2 1/4 inches in diameter with approx 1/8 inch thickness
It looks legit. https://www.apmex.com/product/117914/1876-u-s-centennial-medal-ms-67-ngc-brown https://en.numista.com/catalogue/pieces131453.html hope this helps some.
The mint made these in gold, silver, bronze, white metal and copper. Private contractors may have made more in white metal.
