CLOSTER - A piece of American history sold for nearly $100,000 at an auction Monday.

A gunpowder horn believed to have belonged to Alexander Hamilton was auctioned off at Sterling Associates auction house in Closter. The auction house believes Hamilton traveled constantly with the horn.

The horn has numerous inscriptions on it and forensic handwriting experts believe they were made by Hamilton himself.

Sterling Associates owner Stephen D’Atri says the horn brought in unprecedented amounts of interest.

"During war times, you would have carried it for your rifle,” D’Atri says. “During hunting, all those different sort of things, you would have seen typically at that time period, people carrying it on their shoulders at all times."

Experts believed the horn was going to sell for up to $35,000, but it ended up selling for $94,000.
