Ashley Parchert, 15, of Tennessee, watched Corey's auctioneer-style approach to trading, hoping to pick up a few pointers.
"He's really good. This is only my first time — I just have a few patches," she said, pointing to a small stash on the edge of the blanket from her council. "I'm trying to learn still."
Michael Parker, 17, of Virginia, said patch trading is one of the best things to do at events.
"I'm crazy about it. I've slowly built mine up," he said. "I'm up to 200 patches here."
For Corey, it's all about the customer service. He gives a firm handshake and hello to each buyer.
Others took a less outgoing approach.
Matthew Shore, 12, of North Carolina, was attending his first Jamboree. He showcased his humble collection a few blankets down from Corey.
"Can I give you this?" said Aidan Orr, 12, of Connecticut.
"Hmm. Do you have anything else?" Shore urged.
Orr pulled out a pocketful of other patches, sorting through his top contenders.
One with blue stitching caught Shore's eye, and he outstretched his arm, patch in hand, to signal a trade.
"It's all just an opinion — what you like best," Shore said.
For some, the patch trading was just as exciting as the high-adventure sports at the Jamboree.
"I love this," said Corey LeLathower, 14, of Illinois. "It's amazing to find something you love and something new that you want to keep and not want to trade. Those are the best moments."
