<p>[QUOTE="NSP, post: 8212366, member: 74849"]The 237 survivor estimate is one of the more glaring examples of how inaccurate PCGS’s survival estimates can be. The PCGS population report shows 794 examples, and the NGC census shows 398. Granted, these numbers are inflated by crossovers and resubmissions, but there are almost certainly far more than 237 coins in PCGS and NGC holders. I suspect that the actual number of surviving examples is somewhere in the neighborhood of 2500.</p><p><br /></p><p>One possible explanation for the 237 figure is that maybe PCGS originally chose that number for one of the three die marriages back when they were all recognized as different overdates. Then, once it was determined that all three die marriages were actually 1825/4/2, they adjusted their CoinFacts website to only list “1825/4/2”, but didn’t adjust the survival estimate accordingly. That’s just speculation on my part, though.[/QUOTE]</p><p><br /></p>
