Multiple Card Slabs

BGS_Buyer

Will 3rd party graders ever offer a slab holding multiple cards ?

I've always liked the idea of holding an over-sized slab,
designed to hold multiple cards (2, 3, 4, 6, etc)
for some personal favorites

example, Gretzky, Messier, Kurri, Coffey, Anderson & Fuhr rookies all in one slab with 6 slots & labels

I do remember seeing a PCGS slab with all 5 sizes of Gold Pandas inside one larger slab
I only saw it one times & never again
