Saw the show this past Tuesday,currently running on TNT is Season 4.
This episode was #11 Wagers of Sin
One scene shows Ed with Delinda's help proving his theory that a BJ dealer was palming and switching chips meant for the tip box.
It shows the $100 and the $1,and it appeared to me (being a bit far from the TV)
the chips had the multi-colored inserts,not the simple white ones as the EBAY chips mentioned.Also the $100 was not yellow. FWIW..
