<p>[QUOTE=&quot;bernard55, post: 8136327, member: 114733&quot;]Here is another question I’ve wondered about for years… Can anyone explain how CDN (<a href="https://www.greysheet.com/coin-prices?gclid=Cj0KCQiAq7COBhC2ARIsANsPATHgevl9FpPNjnbp-i7ijMtYYDChq_YziqWtq7XI5KAlQVeElyq5-DUaAp_FEALw_wcB" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.greysheet.com/coin-prices?gclid=Cj0KCQiAq7COBhC2ARIsANsPATHgevl9FpPNjnbp-i7ijMtYYDChq_YziqWtq7XI5KAlQVeElyq5-DUaAp_FEALw_wcB" rel="nofollow">Graysheet</a>), <a href="https://www.ngccoin.com/price-guide/world/" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.ngccoin.com/price-guide/world/" rel="nofollow">NGC</a> (<a href="https://www.ngccoin.com/price-guide/world/" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.ngccoin.com/price-guide/world/" rel="nofollow">NumisMaster </a>for WW), and <a href="https://www.pcgs.com/prices" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.pcgs.com/prices" rel="nofollow">PCGS</a> set their prices in their ‘price guides’?&nbsp; Is it set from auction data found on eBay, HA, GreatCollections, and CoinArchives? …and how often is it updated?</p><p><br /></p><p>Sure, I understand that price and value are different (price being the amount to be paid to get something and value implying the worth of the coin to an individual) and value can never be determined in terms of money and varies from customer to customer. But… my question is, <b>how are these companies setting the price</b> (not value).</p><p><br /></p><p>I also understand the Greysheet represents sight-seen transactions while PCGS/NGC prices are for the sight-unseen market regardless of the coin’s eye appeal representing a ‘floor’ of the lowest prices coins are trading for… but that doesn’t give me any insight into how they set their prices.</p><p><br /></p><p>Is the price determined by supply and demand as in normal markets—I assume it is…? If that is the case and supply is fixed (sure, new hoards can be found) then supply’s impact on price is the assets rarity based on mintage, as well as, the population estimate at each grade.</p><p><br /></p><p>[ATTACH=full]1417841[/ATTACH] </p><p><br /></p><p>… and demand is driven by design (size of Mogan or a thaler is more desirable than a 3 cent nickel), bullion content (intrinsic/melt value), and the ups and downs of gold and silver bullion markets (<a href="https://www.nytimes.com/1983/02/13/arts/numismatics-do-metal-prices-affect-value-of-rare-coins.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.nytimes.com/1983/02/13/arts/numismatics-do-metal-prices-affect-value-of-rare-coins.html" rel="nofollow">link</a>) coupled with disposable income and the % of fear in the general market of an economic downturn.</p><p><br /></p><p><b>But how do these supply and demand variables get used to come up with the published number?&nbsp;&nbsp; </b></p><p><br /></p><p>Many comments in the past have been that ‘the number doesn’t matter’.&nbsp; I get that sentiment but that is more valuable for the ‘value’ side of the discussion. I’m interested here in understanding how they set the price.[/QUOTE]</p><p><br /></p>
