Who doth molest my contemplation?
Is it your trick to make me ope the door, That so my sad decrees may fly away, And all my study be to no effect? You are deceived: for what I mean to do See here in bloody lines I have set down; And what is written shall be executed.

But I am watching it closely... If I am not able to solve the puzzles, at least at criticizing I should be very good... hehe, we have a saying, if you can not convince them, confuse them...

Has anyone found more than one solution or is there only one with the maximal probability?

Just for fun  for comparison: If I check the (49 choose 4) = 211876 combinations for the banknotes and if the code shows only the combinations having a bigger probability than the biggest so far (starting with f.e. 1%), I see N combinations  the Nth being the solution. I don't know, if posting of "N" is spoiling. The solution can be seen after less than one second, the total computing time is less than 3 seconds.

Not sure if it is useful but I am seeing higher probabilities if I ignore "uniquely determines the set" part.
