I know, there are no stupid questions, only stupid answers.... Q: What is the number on the top of the PCGS slabs (such as this slab posted by spock) http://www.cointalk.org/showthread.php?t=34550 What does it signify or what? Thanks!
7524 is the series PCGS defined for that coin - so each coin will have a different series defined by PCGS. The 05893026 is the serial number. Is that what you are talking about? Not sure if I described it correctly.
Minor point of semantics - the first number (in this case, 7524) is the issue, not the series. A series is also known as type - for instance, "type I gold dollars". An issue is a particular item (date / mint / variety) within the series - in this case, 1853-O. So the first number, 7524, tells you it is an 1853-O gold $1. This matches the ID numbers on their census report (available only by subscription). The second number is the numerical grade (in this case, 63). The third number is the unique certificate number (i.e. a serial number). So there will be many slabs with the 7524.63 part, because there are several MS63 1853-O gold $1s. But only one will have the /05893056 part. To make it a little more complicated, the first number varies depending on whether or not it is a business issue (MS, MS-PL, MS-DMPL), or proof (PR, PR-cam, PR-dcam). So the 1884-P gold dollars have several IDs : MS ID = 7585 PR ID = 7634 PR cameo ID = 87634 PR deep cameo ID = 97634 Clear as mud !
Actually..... There are no stupid questions, only stupid people that ask questions! Only kidding. I couldn't resist. The opportunity presented itself and I jumped on it. I love that response though!
