<p>[QUOTE=&quot;robc, post: 1122586, member: 29686&quot;]The test piece work was none with dies made from a master engraving done by Gilroy Roberts; then the chief engraver of the US Mint.&nbsp; INCO paid him to make this engraving to match the configuration of the Kennedy half dollar.&nbsp; The design by Roberts&nbsp; was therefore what one would say is a normal coinage design. We were not a production operation; we were a laboratory development operation that made coinage test pieces to exact production coin sizes and weights to use in typical coin testing devices made by National Rejector and Coin Acceptor. These were the two coin testing devices that were in almost 100% of the vending machines.[/QUOTE]</p><p><br /></p>
