'Seinfeld' Star John O'Hurley Called In for Expert Opinion On 'Pawn Stars'

World renowned traveler and fashion icon, J. Peterman, is used to collecting prized possessions, like President Kennedy's Golf Clubs ... but when he wants to check out some truly unique items he heads to the boys at Gold & Silver Pawn Shop.

Actor John O'Hurley, who played the popular character back in the day on "Seinfeld," recently stopped by the famed pawn shop in downtown Las Vegas, where the History Channel's "Pawn Stars" is filmed.

O'Hurley met with Rick Harrison and Chumlee, and was actually asked to authenticate an item from "Seinfeld" that was brought in by a customer.

The Blast

In a behind-the-scenes shot, obtained by The Blast, O'Hurley can be seen standing at the counter with the customer while she is engaged in negotiations with Chumlee and Rick.

It's unclear exactly what the customer brought in, but we're told the entire thing will be featured in an upcoming episode of "Pawn Stars."

After helping out with the "Seinfeld" memorabilia, O'Hurley took photos with the tons of fans who had lined up outside the pawn shop after word spread that the actor was making a special appearance.

The D Casino Hotel

While staying in Las Vegas, we're told O'Hurley stayed at a suite inside the nearby D Casino Hotel, where he couldn't resist taking a photo-op with the casino's lovely Dancing Dealers.

Andiamo

The star also stopped by Andiamo Italian Steakhouse, where he dined on one of the restaurant's signature 8 oz. filets, which of course he paired with a glass of his favorite vino.
