The American Gun Company was the "house brand" of H&D Folsom Sporting Goods, New York City, c. 1895-1930. The guns were manufactured by Crescent Arms, Norwich, Connecticut. Their single barrel shotguns sold for less than $10 when new. Their double barrel shotguns sold for $10-$15 when new. Old trade-name shotguns are not generally collected and not safe with modern ammunition, so are valued solely as a mantle ornament. The value of these guns if they are broken, badly worn, or rusty is less than $50. In like-new condition, it might be over $200. In "average" condition, it would probably be about $125. Here's verbatum from Standard Catalog of Firearms: "American Gun Co. / Norwich, Connecticut / Crescent Firearms Co - Maker / H & D Folsom Co - Distributor / Side x Side Shotgun A typical trade gun made around the turn of the century by the Crescent Firearms Co. to be distributed by H & D Folsom. These are sometimes known as "hardware store guns," as that is where many were sold. This particular gun was chambered for 12, 16, and 20 gauges and was produced with or without external hammers. The length of the barrels varied, as did the chokes. Some were produced with Damascus barrels; some, with fluid steel. The latter are worth approximately 25% more." Although not mentioned in this listing, there were also single shot break action shotguns similar in configuration.
