Assuming 1.6 billion cards in base set would lead to 1.6 B * 1/3 * 1/11 * 1/15 so 3.23 million of each base holo. Here is a source from 1999 stating 2 million 2 player starter decks were sold at that point. This does nothing to estimate the split between base 1st/shadowless/unlimited/1999-2000. I would also guess this number is a lowball for base. I have heard of an intended 10% 1st edition print run for WOTC sets? (Any thoughts/help here?)
