DENVER -- If the closet, attic or basement needs to be cleaned out, this may be the week to do it. The Treasure Hunters Roadshow is in Denver

But antique store owners want to give sellers a warning: know the value of the item you want to sell.

"It's never been published," said a man wanting to sell reprints of Civil War manuscripts.

It's just one of many military items people brought to the Holiday Inn to sell to Treasure Hunters Roadshow.

"I came down here to sell some silver coins, dollar pieces," said Charlette Tate, of Denver.

Monday people came in with items such as a Tiffany clock, jewelry and gold.

"I've seen them on TV so many times I thought I am going to go on down there," said Tate.

When asked if she was talking about the Antique Road Show, Tate said, "[Antique Road Show and Treasure Hunters Roadshow] are both the same to me."

Actually, the Antique Road Show most people watch on PBS is very different than the Treasure Hunters Roadshow.

"The biggest difference between us is that instead of appraising something and telling you what it is worth and you find the collector, we find the collector and we buy," said Paul Dichraff, regional manager of Treasure Hunters Roadshow.

Dichraff said his company will not buy an item unless they have a buyer.

"We represent 10,000 collectors worldwide," said Dichraff. "We find collectors and purchase it right on the spot. Usually within about seven minutes."

Besides buying items this week, the company is visiting the antique stores on South Broadway to shoot part of a television show.

"We thought that was a great thing," said Kathryn Kramer, of Lucky Jacks Antiques, which will be featured on the show.

But Kramer became concerned after a co-worker did an Internet search.

"Some concerns came up," said Kramer.

For example a story was found about checks from Treasure Hunters Roadshow bouncing.

"Are checks bouncing from Treasure Hunters Roadshow," asked Dayle Cedars, 7NEWS reporter. "No," said Dichraff. '"That is over two years old. We had someone bounce a check to us for $300,000 causing some of our checks to bounce."

So after some reassurance and hearing about how things went at the show Monday, the folks at Lucky Jacks Antiques think they're pretty lucky. And did most of the customers who left the show Monday.

"It was a great venture," said Tate, who didn't sell a thing. "I found out a lot about the coins that I had, so that was good."

Kramer said if a person plans on selling something at the Treasure Hunters Roadshow, they should have the item appraised ahead of time so they know what the item is worth, or at least what someone is willing to pay. She said a person can do that on eBay or by coming to a local antique shop and asking around.

Once the Treasure Hunters Roadshow makes a person an offer on an item, the person can still take the item to get an actual appraisal before deciding to sell.
