I've got plenty stashed away for a rainy day - more so quantity than quality but the Big O RC is a definite exception! I should try to recall how many of your former cards I actually have - that could be close to 300 as well! heh heh
I have had a lot of very nice cards over the years, Lebron autos, Ewing autos, Russell Wilson autos. But this cheap (compared to the other names listed) Alex Brosque auto is the one I have been most happiest to own. Being a massive Sydney FC fan and Brosque being my favorite ever Sydney player I was over the moon when this Jersey Number auto came up on eBay, even better that I got it for half of what I bid.
