When experts opened a West Point time capsule, they found nothing. The box turned out to hold hidden treasure after all.

West Point historians open lead box hidden in 194-year-old statue

A nearly 200-year-old West Point time capsule that appeared to yield little more than dust when it was opened during a disappointing livestream contained hidden treasure after all, the U.S. Military Academy said Wednesday.

It was just more hidden than expected.

The lead box believed to have been placed by cadets in the base of a monument actually contained six silver American coins dating from 1795 to 1828 and a commemorative medal, West Point said in a news release. All were discovered in the sediment of the box, which at Monday's ceremonial opening at the New York academy appeared to be its only contents.

"When I first found these, I thought, man, you know, it would have been great to have found these on stage," said West Point archeologist Paul Hudson, who after the event, took the box back to his lab and began carefully sifting through the silt with a small wooden pick and brush.

"Before long, lo and behold, there's the edge of a coin sticking out," he recounted by phone, "and I thought, well that's OK. That's something, that's a start."

He said he was as disappointed as anyone by the underwhelming results of the live opening, which brought comparisons to Geraldo Rivera's televised 1986 unsealing of a Chicago hotel vault purportedly belonging to gangster Al Capone, which infamously revealed nothing but dirt. A crowd that had gathered at the U.S. Military Academy had hoped to see military relics or historical documents when experts pried open the top and pointed a camera inside.

The event was live-streamed and cadets were filmed giving their own predictions for what was inside the box.

As archeologists pried the lid off the box, there was laughter as it dawned on everyone the box was basically empty, except for some silty material sitting on the bottom, CBS New York reported.

"Little disappointed. We built up to this quite a bit, and I'll tell you the truth -- that was the last outcome I expected," Hudson said.

Then came the discovery of the hidden coins and medal.

Hudsin said it was probably better to extract the coins and medal in a controlled setting anyway. He still plans to analyze the sediment for more clues about what else may have been inside.

It appeared that moisture and perhaps sediment seeped in to the box from a damaged seam. The conditions also could have disintegrated any organic matter inside, like paper or wood.

What did survive were a 1795 5-cent coin, an 1800 Liberty dollar, 1818 25-cent coin, 10-cent and 1-cent coins from 1827, and an 1828 50-cent coin. There was also an Erie Canal commemorative medal dating to 1826.

Various expert websites indicate the potential value of most of the coins, depending on the condition, is between a couple hundred dollars to well over $1,000.

The finds seem to confirm academy officials' theory that the box was left by cadets in 1828 or 1829, when the original monument, which honors Revolutionary War hero Thaddeus Kosciuszko, was completed.

A committee of five cadets that included 1829 graduate Robert E. Lee, the future Confederate general, was involved with the dedication of the monument.

Kosciuszko had designed wartime fortifications for the Continental Army at West Point. The Polish general and military engineer who fought in the American Revolutionary War as well as an uprising in his home country .died in 1817. A statue of Kosciuszko was added to the monument in 1913.

"This is an incredible story that involves so many of West Point's heroes and many of them are the Army's and our nation's heroes," U.S. Military Academy's Dean of the Academic Board Brig. Gen. Shane Reeves said in a statement. "We should reflect upon and be inspired by our history to pause and realize we have the immense honor and responsibility to continue the legacy that Kosciusko started, and that West Point continues to live up to his vision from so long ago."

The historical preservation and analysis of the time capsule will continue.

"I think there's more that we can learn from this," Hudson said, "to learn about the academy's history and about the country's history."

When the monument is rebuilt, West Point will place a new time capsule inside, to be opened at a later date, CBS New York reported.
