An East Coast autograph broker told ESPN on Tuesday that Johnny Manziel was paid $7,500 for signing approximately 300 mini- and full-sized helmets on Jan. 11-12 while he was attending the Walter Camp Football Foundation event.

The broker played two cell phone videos for ESPN showing Manziel signing white Texas A&M helmets and footballs laid out on a bed in a hotel room. The video does not show Manziel accepting any money.

The broker said the room was at The Omni in New Haven, Conn., during the Camp event. He said the signing took place at three different times on Jan. 11-12, totaling about an hour.

The broker and his partner originally requested money to release the videos for use on ESPN, which ESPN declined to pay. The broker did allow ESPN's Joe Schad to view the videos. Later, the broker said he had decided not to sell the videos.

The broker said the videos, approximately nine minutes in length in total, were initially shot only to be used as proof with authenticating company PSA/DNA.

On the videos, which the broker said were recorded without Manziel's knowledge, ESPN heard Manziel say "you never did a signing with me" and that if the broker were to tell anyone, he would refuse to deal with him again in the future. Manziel, who appeared comfortable throughout the video recordings, also said if asked, he would say he had simply been approached by various autograph seekers.

At one point, ESPN heard a broker ask Manziel if he would take additional cash to sign with special inscriptions, but Manziel declined, indicating he had done that before and it led to questions. The video does not show Manziel accepting cash, which the broker alleges happened three times. The broker told ESPN that Manziel said he wanted money for new rims for his vehicle.
