The common Magnetic 1942-1943 P nickel. No big deal.
I was interested after reading a recent post about these magnetic Jefferson nickels. Being a fan of the series I had a couple rolls of “war” nickels around so I searched a softball sized bag and found 8 that stick to a strong magnet. This magnet is a useful tool for a variety of electrical and manual labor tasks as well as being incredibly strong, so I used it. Something about some 1942 P and 1943 P nickels is just magnetic. If you search your own rolls you will find them too. No big deal.
Curious that it is only these two years and both are Philadelphia mint marks.
