The site Coinflation tracks the melt value of US coins.

BTW: The reason we keep the penny is because local tax tables calculate taxes to the penny. Local tax collectors are strict about collecting taxes to the penny.

Companies caught rounding to the dollar face harsh treatment from the tax collector.

I suspect that the Feds like the fact that calculating to the penny raises the cost of doing business in cash.

BTW: With the falling price of the US dollar, I often wonder why HIVE inflicts harm on the Hive-O-Sphere by pushing HBD. HBD is destined to fall with the dollar.
