<p>[QUOTE=&quot;ksmooter61, post: 26571623, member: 169607&quot;]As far as how many machines used to produce cents at any given time, there are currently a total of 63 in Philadelphia and 54 in Denver. They would have several down at any given time for regular maintenance, so in Denver maybe 40 are running (guess #1)? Looking at production numbers from Denver in 1971 there were (in millions):</p><p>1¢ - 1,911</p><p>5¢ - 316</p><p>10¢ - 378</p><p>25¢ - 258 (hard to believe; more dimes, nickels &amp; <i>halves</i> made than quarters)</p><p>50¢ - 302</p><p>$1 - 68</p><p>A total of 3,233 million coins. The machines run at 750 coins per minute (all denominations run at the same speed). If the Denver mint worked only dayshift for 8 hours for 200 days that year that would be 1,600 hours, or 96,000 minutes. At 750 coins per minute, you get 72 million. Multiply that by the 40 machines you get 2,880 million, a little less than the reported total of 3,233 million, but I believe (guess #2) they would run two shifts during busier times. Cents were nearly 60% of production so would probably require the same ratio of presses (guess #3). 60% of 40 presses would be 24.</p><p><br /></p><p>My guess (#4) is 24 presses running at any given time in 1971 to make cents. However, I have absolutely no idea about the bags or bag loaders, nor can I find any information on them. A final guess (#5) would be 1 loader for 6 presses.</p><p><br /></p><p>This is like a 5-game parlay, where at even odds you would have a 1 in 100,000 chance of winning, but I will put it out there - 24 total presses, 6 presses per bag loader.</p><p><br /></p><p>Regarding the chances of a bag holding multiple coins that were produced around the same time and from the same machine, I asked a while back concerning Morgans and was told by some here that was patently impossible due to the way they were handled after being struck. I still believe coins minted consecutively would have a <i>better chance</i> of ending up in the same bag in the end.[/QUOTE]</p><p><br /></p>
