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 !
