I'm pretty sure the same amount of all the OG 1's (minus the black/gold) were made in the same numbers, just different demand and that magic word we've been throwing around in terms of royals, "allocation". This release is just an aftermath of the royals. Nobody wanted to miss out on these, even if they didn't truly want them the resell value was enough to make everyone want to grab these.
Oh and not to toot my own horn but remember a couple months back when I was saying these would resell for whatever royals were going for on the market by the time they released, and would eventually go for $600....and a couple scoffed at me claiming GR, it's Christmas and its a black/red colorway so that = abundant pairs
