<p>[QUOTE=&quot;mikediamond, post: 6597175, member: 1859&quot;]It&#039;s not a Malaysian 1 sen planchet, as those are composed of copper-plated steel.&nbsp; The OP&#039;s coin is composed of copper-plated zinc.&nbsp; It&#039;s also not a Singapore cent planchet.&nbsp; While those are composed of copper-plated zinc, they are much lighter at 1.24 grams.&nbsp; These wrong planchet Lincoln cents vary quite a bit in weight, falling between 1.5 grams and just over 2 grams.&nbsp; They seem to have a bimodal distribution, with most falling at either 1.7 grams or 2 grams.&nbsp; They mystery remains as to what these planchets were intended for and whether they represent&nbsp; two (or more) unrelated populations.[/QUOTE]</p><p><br /></p>
