That is a first generation ANACS holder (ANACS 11). They started using that holder around December of 1989. (Before that time ANACS used photocertificates 1972 - late 1989). ANACS was sold to Amos Press in February of 1990 and these slabs were used for a little while longer until Amos Press could have their own hologram developed. So this slab was in use from around Dec 1989 to possibly May of 1990.
