Does anyone have a 1942 nickel stamped with the?

I am guessing that you mean a 1942 nickel with the mint mark prominently stamped on the reverse above Monticello. It may be either a D,S or P. These are special wartime nickels that contained 35% silver. 56% copper and 9% manganese They were produced through 1945 and in huge numbers. They are generally worth the value of the silver in them, about $1.60 today. High grade uncirculated coins will have a premium value depending on year and mint.
