Is a matching set of shotguns rare and valuable?

Answer 1

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 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 mantle ornaments.

The value of these guns if they are broken, badly worn, or rusty is less than $50 apiece. In like-new condition, it might be over $200. In "average" condition, it would probably be about $125-$150 for the 12 guage. The 410 might bring about twice as much from the right buyer.
