As hindu mythology Copper coins are symbols of goddess lakshmi, copper coins should be placed in pooja/puja temple, office and home. According to science of spirituality the articles prepared from copper have an important place in deity worship. This is because copper has 30% capacity to imbibe sattvikta (the quality of sattva) when compared to other metals. Besides it has also 70% ability to destroy the raja-tama. Just as copper has the ability to absorb the sattvik frequencies of deities, it has also capacity of transmitting them. Thus it becomes rich in divinity in a short period. The sattvik frequencies of deities are then transferred to other components of puja. Therefore copper is considered an auspicious metal.
