The hand that Mary is holding for her husband Meredith is the 4 and 6 of clubs, 5 of diamonds, 6 and Queen of hearts, a very poor hand. ADDITION: This may be the hand that she shows when asking for the loan; but earlier, in the poker room, she flashes a 10 (of diamonds or spades)in her hand when speaking and gesturing to her son. What the hand was actually supposed to be apparently was not germane to the plot and the actual cards used for the hand were apparently changed from scene to scene as the viewer was expected to always wonder what the hand really was (and not pay such close attention).
