This is an silver medal from the Medallic Art Co. "Declaration of Independence" series. There were 56 medals in this series, one for each of the signers. The portrait side is in very high relief, the reverse has a little about the signer.
This is from a relative's estate, and is in mint condition. It is 1 1/4" in diameter and has a matte satin finish. According to the information I have found, these medals contain about .8 troy ounces of .999 pure silver. These medals were produced about 30 - 40 years ago.
We have other similar medals and will try to list them soon, but if you are looking for a special one, just ask. I am not an expert on coins or medals, but am happy to try to answer any questions.
