I recently got a medal from 1973 commemorating the second inauguration of President Richard Nixon from my local coin shop (I like the reverse design but honestly I mainly got it for the neat little wood-grain style stand it came with) and after some admittedly brief surfing I did not find details on the specific type online but I would guess it to be an official US Mint bronze medal, with it measuring about 33-34 millimeters and possessing what appears to be a Denver Mint mintmark on the obverse at about 5 o'clock. The weight is 18.3 grams.
