ATTLEBORO - Soon, there will be few local traces left of Jostens, once a powerhouse in class and commemorative ring making and a cornerstone of the Attleboro jewelry industry.

On May 20, a Rhode Island auction and appraisal firm will auction off the entire contents of the company's plant, which until recently employed up to 275 people. The company closed the plant in February, moving all production to Texas.

The auction begins at 10:30 a.m. at the Jostens plant.

The auction includes all of the company's machinery and equipment, but no dies or tooling, said Michael Salvadore of Salvadore Auctions and Appraisals.

Items to be auctioned include finishing equipment, powder coating lines, dust collectors, ultrasonic cleaners and an entire machine shop. Controlled inventory carousels, compressors, jewelers bench equipment and tools and office furniture will also be sold. Salvadore said the sale has attracted interest from around the globe, including companies in Russia, Iran, Southeast Asia and Central America.

"This is one of the premier manufacturing facilities around and has modern up-to-date equipment" Salvadore said. "We will be selling certain asset segments both live on site and live online to a global audience."
