PSA faces collector backlash after grading problems at national convention in Rosemont

ROSEMONT, Ill. - The National Sports Collectors Convention drew thousands of collectors to Rosemont last weekend, but one of the industry's largest card-grading companies is now facing backlash.

Some customers say Professional Sports Authenticator, better known as PSA, promised on-site services it could not deliver.

PSA faces collector backlash after convention in Rosemont

The backstory:

Customers at the five-day convention paid hundreds of dollars per card to have their collectibles graded and returned before the event ended.

PSA is one of the world's largest and best-known card authentication and grading companies. But by the end of the convention's opening day, overwhelming demand forced PSA to "suspend its on-site Express submissions."

Customers whose submissions could not be completed at the convention were told their cards would be mailed back, frustrating some collectors.

Dig deeper:

This comes as the company is facing legal action out of California for allegedly acting in bad faith and engaging in fraudulent business practices. 

Separately, PSA has been named in a proposed class-action lawsuit that claims misleading marketing and inconsistent grading practices.

FOX Chicago has made multiple attempts to reach PSA for comment but has not received a response.
