<p>[QUOTE="dougsmit, post: 2411445, member: 19463"]I do not consider 1965 Kennedy's fourree because they are not plated on the edges but sandwiched. The fourree of current note is the copper over zinc Lincoln cent. Actually I really prefer to reserve the term fourree to that group of plated coins made by wrapping silver foil around a copper core and striking the hot mess hard enough that the two layers are bonded. If you use enough heat and pressure, a thin layer of silver solder 'glue' is formed between the layers. Some fourrees were made with a powdered 'eutechtic' sprinkled between the layers when the packet was wrapped materially improving the chances of a firm bond. All this is explained well in the William Campbell book I quote here every chance I get but I wonder if anyone reads. </p><p><a href="https://babel.hathitrust.org/cgi/pt?id=inu.30000104992965;view=1up;seq=7" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://babel.hathitrust.org/cgi/pt?id=inu.30000104992965;view=1up;seq=7" rel="nofollow">https://babel.hathitrust.org/cgi/pt?id=inu.30000104992965;view=1up;seq=7</a></p><p>You can buy a copy for $30 but recently it was put online with the other ANS monographs so you can read it free. </p><p><br /></p><p><img src="http://www.forumancientcoins.com/dougsmith/4jdedge.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>The above shows an edge view of a later (Julia Domna) foil fourree which has chipped at the edge showing how thick the silver is.
