Message:: [QUOTE="kanga, post: 3576179, member: 9270"]Just received my latest copy of COIN WORLD WEEKLY (June 24, 2019).One of the two first page articles is titled "NGC confirms 1943 tin cent".We've been inundated with:-- is my 1943 "penny" silver?-- has my 1943 cent been struck on a dime planchet?-- is my 1943 cent copper?-- is my 1944 cent on a 1943 planchet?-- other variations on a 1943 find? We can now prepare ourselves for the newest version of the question."Is my 1943 'penny' made of tin?" According to the article it took "... a nondestructive metallurgical analysis, an X-ray fluorescence, or XRF, analysis."The result: "... 86.41 percent tin, 8.37 percent antimony, 1.75 percent copper and 1.02 vanadium."The weight is 2.7 grams vs. 2.69 grams for the standard 1943 cent. At least we can tell the person asking the question to submit the coin for "a nondestructive metallurgical analysis, an X-ray fluorescence, or XRF, analysis."I bet THAT'S a pricey test.[/QUOTE]
