convert cell array into double and remove dollar symbol

Hi everyone, I was working on an assignment and I got stuck into converting a cell array of the type: a = {'$12,001.87','$0.04','$12,003,887.55','$0.32'}; into numeric values that I can finally sum up. I tried str2double but I have got NaNs probably because of the dollar symbol that I should remove (not sure though). Can someone please help me with this?

C = {'$12,001.87','$0.04','$12,003,887.55','$0.32'};
C = strrep(C, '$', '');
C = strrep(C, ',', '');
N = str2double(C)
