    "Auto White Balancing" actually makes coin photos more unreliable in color on anything but blast white coins. Gold and copper/bronze coins will always mess up AWB. Manual white balancing specifically matching your light source is required. Watch anyone setting up a video shoot. They spend time white balancing on a white card, specifically because AWB is so unreliable. Yet most inexperienced coin photographers blindly use AWB, and get strange colors on their non-white coin photos. Manually set your white balance on a CLEAN white card under the lights you'll be shooting with, for best results. If you're using a camera phone, this will require a "fancy" app, not the one that came with the phone/camera.

    Ok nice thank you

    Recycled shell casing were used  as long as they were available - well into at least 1948. Most of these were 50cal. from domestic training camps. Large artillery shells in Europe were given to local governments so the metal could be used for infrastructure repairs. Naval shells were commonly dumped overboard, and some Asian materials were shipped to Hawaii for recycling. (The stuff was too bulky to use as ballast and there were no local facilities for rolling out the cases.)

    Cents were made from the same alloy whether or not shell cases were used. This was about 95% Cu and 4.5% zinc with a trace of tin from May 1942 forward.

    The coin pictured might be simply discolored, plated, or struck on a foreign brass planchet. As kbbpll notes, there were no 1944 experimental pieces recorded. Readers should be extremely skeptical about any photos that claim to show correct color - achieving this beyond the experience level of most, even with "auto white balancing" and other things. :)

    Thanks for all the good info taking the time

    Actually it's zinc-plated steel as all 1943 cents are. Any 1944 transitional errors would have the look and magnetic properties of a normal 1943 cent, but with the 1944 date.

    The historical irony here is that zinc was used as the plating metal in 1943, but since 1982, the zinc is the inner metal onto which copper is plated. Zinc is funny stuff. Some wartime European coins were zinc through and through and they oxidize white, as all zinc oxide is white. It also keeps your nose from burning in the sun. Zinc oxide is in many sunscreen products.

    Awesome thank you.
