Just to tell you our experience before, this is not the first time a special edition was issued. Some years ago, a special edition THB100 was also issued, backside picture was also different from the regular series but it all went to reject, attached is the sample picture. No fine tuning was done on the regular series. This is the same situation now for the THB500, only the backside picture was changed with no security features, that is why we are surprised this time some goes to reject, some goes to stacker. Our customer would like to know what is the difference between the THB100 and the THB500 now. How much then it would cost if they only require to go to reject?
