India has been known to immortalize its heroes and significant events in the form of stamps and coins. This has been going on for ages. Every government issues new coins, whether gold coins or coins of other materials like silver, etc.
The gold coins come in 1 gm, 5 gms, 10 gms and other denominations. The small size is due to the fact that gold id a costly and rare element and it takes a lot of time to extract it and purify it from its raw core.
Gold coins are given on special occasions like festivals like Diwali, Laxmi Pooja, etc. and the 1 gm coins are the ones that are exchanged between people in most of the cases due to the fact that they are the cheapest ones available. The receiver never looks at the size, he just appreciates that someone has dished out a gold coin to him and this acts as a mental satisfaction to the receiver.
Gold coins can also be presented by big corporate companies as a mark of achieving any distinctions like completing 25 yrs, 50 yrs, 100 yrs etc. This occasion means a lot to the founders of the company and hence, to commemorate the event, the company dishes out gold coins to its employees. This is surely a welcome bonus for the employees and it does make the employees thing twice before joining some other company. The gold coins can be given as a pure gold coin and they can be given out in the semi gold form as gold plated coins, which cost lesser than the pure coins.
Gold coins are definitely not the ones used for a toss before an important football match; they have a far better value and even better uses.
