This photo does not appear legitimate to me. I'm sure the credits are correct but not the dollar value.
The win was $120,000? That would mean about $40,000 was on the machine?
Look at the numeral 6 in the credit total. One 6 is squeezed as you might see in a doctored photo.
Of course if we knew the casino we could easily call to see if the $10 denomination is offered.
