For the first time we can figure out how many packs were printed. If there are only 40 of each gold border, and they are found in one of 204 packs, then there must be exactly 72 x 40 x 204 = 587,520 packs.
Golds are not placed systematically in packs and boxes, instead they have been throougly randomized. You could find one gold, and with probability 1/204 find another one in the next pack even if in the same box.
At the extremes, one collector went 1200 packs in a row without finding a gold, while another lucky collector pulled 32 golds out of one 16 box case of 24 pack boxes. The latter was certainly a fluke, it seems they put golds in place of silvers in that case. Somebody pulled two out of the same pack, though that was also certainoly a mistake. For the most part they do seem to be completely random. We have heard golds are being pulled with the correct odds from all types of different boxes, blister packs, bonus boxes, gravity feeds. Besides a few small glitches they did a pretty good job of randomizing them.
Some have speculated that you are less likely to find a gold in a bonus box than in six regular packs, because you know one pack has the bonus sticker and therefore cannot have a gold. If the bonus sticker is put in a pack that could displace another insert then this could be true. However if the bonus sticker is always put in a pack that wouldn't otherwise have an insert then this would not be true. The two possibilities would lead to two different numbers of insert packs in a bonus case. A case has 16 boxes, so 96 packs, 16 of which have the bonus sticker. Given the insert ratios printed on the packs, and the fact that you never get more than one insert in a pack, 1/3+1/6+1/12+1/12+1/204 percent of regular packs should have inserts. So if the bonus pack could replace any pack, then we'd expect 16 + 80(1/3+1/6+1/12+1/12+1/204) = 69.725 insert packs in a case. If the bonus pack never replaces an insert pack then we'd expect 16 + 96(1/3+1/6+1/12+1/12+1/204) = 80.47 insert packs in a case. We counted the insert packs in two cases. One had 80 insert packs and one had 81 insert packs for an average of 80.5. Therefore we conclude that the bonus pack never displaces a gold and you have just as much chance of a gold (or any isnert for that matter) in a bonus box as six regular packs.
The following are your odds for finding golds in a box of 24 packs:
