In this special episode of Sports Card Grinders, Will Priester and Renelle Pesigan join Simon Edwards to talk about the epic Cam Newton rookie card flip they all profited from. When Cam Newton got signed by the New England Patriots, his rookie cards shot through the roof and the Sports Card Grinders were all over the flip recommending buying Cam's rookie cards as recently as last week. This recommendation led to a 10x return on investment for viewers and RotoGrinders Sports Card Discord members who bought Cam's cards along with the hosts. Find out who they will speculate on next! #camnewtonrookiecards #camnewtonpatriots #sportscardinvesting
