The Ohio Valley Refinery & Roadshow is in Minden through Saturday in search of rare and unique collectibles.
Collectors have set aside $300,000 to be distributed to Minden residents for their items during the free five-day event.
"The Ohio Valley Refinery & Roadshow makes offers based on what collectors are willing to pay," said Matthew Enright, Vice President of Media. "After one decides to sell an item, he or she is paid on the spot."
More than 1,000 people are expected to attend the event, which kicked off earlier this week.
"Collectors are very serious about their hobby and will pay a lot of money for the items they are looking for," Enright said. "Nearly all coins and paper currency, vintage jewelry, war memorabilia, musical instruments and toys made prior to 1965 are highly sought after by collectors.
"What we've really seen a ton of is gold and silver," he continued. "With both hitting all-time highs and with the state of the economy, people everywhere are cashing in broken chains, necklaces and rings and taking advantage of the market."
The Ohio Valley Refinery & Roadshow is able to offer fair prices because it has its own refinery operation.
All local area businesses that deal with precious metals are encouraged to call ahead and make an appointment with one of their representatives. There are no appointments needed for the general public to sell their items.
The event is free and there is no limit to the number of items that can be brought in.
It takes place at Holiday Inn Express on Sibley Road. They will be open until 6 p.m. Friday, and Saturday hours are from 9 a.m. until 4 p.m.
