<p>[QUOTE=&quot;TIF, post: 2306450, member: 56859&quot;]Thanks everyone!&nbsp; I&#039;m glad you found the electrotyping video helpful.&nbsp; I still have questions about the process as it relates to Ready&#039;s methods for the BM coins:</p><p><br /></p><p>1.&nbsp; Was only the first replica of each coin made by electrotyping, with subsequent copies made by lost wax casting, using the electrotype replica as a the master?&nbsp; (I&#039;d guess not, otherwise why not just make a master mold directly from the original coin?)</p><p><br /></p><p>2.&nbsp;&nbsp; What metal was used to fill the electrotype &quot;shell&quot; prior to soldering the halves together?&nbsp; My replica weighs 16.64 gm.&nbsp; The host coin weighs 13.19 gm.&nbsp; Is the heavier weight due to added thickness or to a different metal?&nbsp; Of the possible filler metals, lead would seem the most likely but its atomic weight is almost twice that of silver so if it were used, the replica weight would be even heavier.&nbsp; My best guess is that the two halves joined together ended up thicker than the host coin, hence the heavier weight.&nbsp; I&#039;m not sure what to guess about the filling metal.&nbsp; Copper is significantly lighter than silver so if it was used as a filler, given the heavier weight the replica would be markedly thicker than the host coin.</p><p><br /></p><p>3.&nbsp; If each replica was made by electrotyping the original mold, how long did each mold last?&nbsp; Do they degrade and lose detail over time?</p><p><br /></p><p>I intend to write the BM to see if anyone there can answer these questions.[/QUOTE]</p><p><br /></p>
