Red hologram or silver green? And if it is barcoded 17 or 19 characters?
The very first small slabs (ANACS 11) when it was owned by the ANA had Official ANA Grading as the underprint. Once they were purchased by Amos Press the underprint changed to ANACS and that stayed from early 1990 to Feb 2006. But there are at least five diferent varieties duing that period.
ANACS 12 No bar code red hologram 1990 - late 91 or early 92 ANACS 13 with 17 character barcode early 92 - 1997 ANACS 14 silver green hologram 1997 - April 2000 ANACS 15 19 character barcode April 2000 - August 18th 2005 ANACS 17 changed font August 18 2005 to Feb 2 2006.
ANACS 12 - 14 may also come in two different sizes of shell. ANACS 11 was made with a smaller size shell and at some point they introduced a shell about 1 mm larger in both height and width. But there seems to be some unknown time overlap when both shell types were used, and possibly for more than one variety. I suspect they kept one sonic welder in use to use up the old shells and switched the others to the new shells, then it took some time before all of the old shells were used up.
