If you lost 50 pounds it would be really noticeable. Your face and stomach would be smaller than it was before.
The same as it does anywhere else. (I tried to interpret this as generously as possible, but sorry, that's it. The Vietnamese currency is the dong, so "50 dollars" is not a valid denomination for a Vietnamese bill.)
Face value to $70 depending on condition
A perfect, uncirculated $50.00 bill is worth $60. In any other condition is is worth face value ($50).
