<p>[QUOTE="manny9655, post: 4835805, member: 112417"]Correct. The color of the coin itself is off, too, as if it had been subjected to some serious heat. To solder something to a copper cent it would take a few minutes to get the copper hot enough to make the solder flow. Leaded solder melts at about 360 degrees F. Lead free solder melts at about 428 to 464 degrees F, depending on the type. You would have to get the cent hotter than that to get the solder to flow. You have to crank your iron well above the melting point in order to get the surfaces involved to accept the solder. It also depends on WHAT you're soldering.[/QUOTE]</p><p><br /></p>
