Hi Atla,
What is the issue you are facing in this code?

This trigger fires Before Insert. If you want it to trigger After insert you have to change the first line to
trigger coin on Contact (After insert) {
Is this u want?

Hi Atla,

A batch apex can be called from a class as well as from trigger code. But, we have to be very very carefull while calling a batch apex from trigger.
  
// BatchClass is the name of batchclass
BatchClass bh = new BatchClass();
Database.executeBacth(bh);

My only concern is that the Trigger would fire on the DML events and that would invoke the Batch.Do you want to run batch as many times as the Trigger would fire ?? Then you can proceed, but my personal openion is not to go with it.
