WEBSTER, Fla. -- A Central Florida coin dealer got more than he bargained for after a day of selling at a Sumter County flea market. He was on his way home with a carload of merchandise when his vehicle broke down, but the worst was yet to come.

The Webster Flea Market is open only on Mondays. The people who set up shop there have never had to worry about being robbed. But now, they might have to think twice.

The coin dealer, identified only as Roger to protect his identity, nearly lost his life on Monday after a day at the flea market. He was headed home on County Road 475 when his car broke down. Roger was looking under the hood when a vehicle carrying three men pulled up behind. One of the men walked up and Roger thought he was going to help out.

But then, the man said, 'I recognize you. You're the guy who sells coins at the flea market.' Roger said, 'Yeah' and the man pulled a gun and said, 'Get on the ground.'

"I thought he was gonna kill me. He could have easily done it," Roger said.

Roger said the robbers cleaned out his truck, stealing nearly $20,000 worth of rare coins. Detectives believe the hold-up had been planned out.

"Well, it would have been quite a coincidence if they just happened upon him. It sounds like they were probably following him," said Detective Andrew Wills, Sumter County Sheriff's Office.

Roger was able to give a description of only one of the suspects, a man around 30 with a medium build, shaved head and a tattoo of a scorpion over his left ear.

"Well, I'll tell you. That's a great identifier. Somebody is bound to have seen this gentleman somewhere," Wills said.

"Brilliant red scorpion. Outline in blue. I'll never forget it," Wills said.

If that scorpion tattoo rings a bell, call the Sumter County Sheriff's Office. There's a reward if the tip brings an arrest.
