Look at the nearby address, add a DWBF data (data 2) under this data, and change both data to data 2 minus 90000000 (brush 900 million, data minus 900 million, brush 800 million and data minus 800 million), then the copper coins will be modified successfully, and the last five will be gold coins. Just follow the copper coin method. Remember that gold coins can't be modified too much or they will flash back. When I revised them at most, it was only 12 thousand.
