How is coin currency made?

  Use of coins was first done by Sumerians where they thought that exchanging coins is better than exchanging barley. Soon, gold, silver and copper coins came into circulation.  But how is this coin currency made?

  In making of coin currency, first long metal strips arrive at the press. Then they are rolled and coiled. Then each coil is put in a blanking press which punches out small coin like discs called as blanks. The remaining metal is used again after recycling.

  Then the blanks are heated to soften them. Then they are washed and dried. Then the coins are inspected and faulty coins are separated according to wrong shape or size. 

  Next the blanks go into an upsetting mill where their rims are raised around the edge. Then they go to a coining press where they are stamped with designs which make them genuine country coins. Then all coins are inspected, counted and bagged. 

  Then they become ready to be used. If you want to know how is paper currency made, click here.

Posts before October 2021 have been marked as "Old Posts". Less likely, but they might have out dated or incorrect information, ugly looking bits of code, no labels, etc. Don't get me wrong, many of these posts are top-notch and interesting too.

I thought it would be better not to delete or revamp these posts, even if they suck. The bitter truth is that old works always suck, but I take that as a positive tool to convey that I am growing. Besides there's no better way to showcase my journey without these old, messy, poorly written posts!
