A coin with a doubled mint mark is called a RPM, short for re-punched mint mark. These exist in all denominations and over many different years. The Lincoln cent and Jefferson nickel are the coins with the most well known RPM's. There are literally thousands of different varieties of RPM's, so it's hard to narrow down which is the one you are referring to.
it is located at the side of the rotary injection pump
For an NPR the rpm sensor is located left rear of engine by the frame rail. Its actually the engine speed per service manual but when you need to replace the sensor the parts department calls it the rpm sensor. Good luck.
replace the printed circuit board behind the tach gauge. $15.00
