Hello,
Where can I find accurate mass and dimensional values for pre-1982 and post-1982 pennies? On wikia, it says 3.1 (pre-1982) and 2.5 (post-1982), but I take these values with a hint of skepticism despite my lab calculated values are very close to them. Can anyone here verify these wiki values with creditable source? Apparently, a post-lab question requires that I cite where I find the actual mass and dimension of these pennies.
Thanks!
