I guess the task of finding such meaning is very difficult. But for Patrick, who suggested a meaning of coin counter ( am I right?), no one could hazard a guess on the economic meanings of the word Arya.
For eg., check this site. It offers manifold meanings of the word Arya (the correctness of which is not of immediate interest) yet, there is nothing economical in that:

I do understand that there NEED not be any economic meaning of this word as such, yet I am not sure we have explored all the possibilities.
hope the group will come out with more possibilities, without any hard feelings,
