<p>[QUOTE="MontCollector, post: 2795578, member: 85496"]They don't. Simple answer is a 1982P Small Date Bronze does not exist. A lot of Lincoln cents were bronze before 1962. Some had a composition of 95% copper and 5%tin and zinc. These one with the tin are bronze. Mix Copper and Tin and you get Bronze. All LWC's from 1909-1942 had this composition. They used this composition again after WWII for all Lincoln cents up until 1962. </p><p><br /></p><p>After 1962 All LMC's until 1982 were composed of 95% copper and 5%zinc.
