<p>[QUOTE=&quot;Conder101, post: 3650740, member: 66&quot;]The 1983&#039;s was the first year for the proof copper plated cents.&nbsp; 1982 and 83 are known for serious problems with the copper plating.&nbsp; The 82 proofs were still made of copper so 83 was the first year gaining experience with the copper platting on the proofs.&nbsp; One thing the learned was they had to increase the plating thickness on the proof planchets to help avoid the &quot;orange peel&quot; problem and to cut back of the spilt plating problem.&nbsp; (The plating frequently splits around the outer eadge of the lettering on business strikes, and with the double strikeing done on proof coins it was an even greater problem.)[/QUOTE]</p><p><br /></p>
