Preservation of cultural property for the future is one of the most important activities of our society. The information which we can gather from such materials is a valuable key to understanding the past. Recent developments in laser techniques in the conservation field have allowed us to test the laser cleaning , Although laser cleaning has gained acceptance in other areas of conservation (e.g. Stone statues and paintings) the process has not been widely applied to metal artifacts of historical value. The potential of laser techniques in conservation has needed a long development period to be fully demonstrated. The possibility to achieve a very precise and selective removal of deteriorated materials was implemented through a series of interdisciplinary studies focussed on laser ablation of specific materials .Therefore, the research will discusses and evaluate the use of laser as a modern technique for cleaning  an archaeological coins with multiple experiments of another researches.
