<p>[QUOTE="messydesk, post: 26695178, member: 1765"]PCGS uses a different scale -- the PCGS CoinFacts Rarity Scale™. It's a classic example of precision without accuracy, having 92 different rarity numbers from 1.0 (> 1,000,000) to 10.1 (none known). As the PCGS CoinFacts Rarity Scale™ is a registered trademark of PCGS, it's unlikely that anyone else will use it. The traditional 8 numbers is sufficient and well-understood (unless you're a CWT person, then you have 9).[/QUOTE]</p><p><br /></p>
