I was unable to find any references to the animal portrayed on San Marino's 1975 10-lire coin. So I had to do it the hard(er) way, and have tentatively concluded that the coin shows a pair of Alpine Marmots.
I previously thought they were European Minks. However, they would be a little stocky for minks. On the other hand, they are on the slim side for marmots and the tails are way too long, as in mink long.
