*ISSUE RESOLVED*
I just wanted to update (for anyone searching for this same problem in the future!) that after ~4 days of being on the Gold Exchange, my gold lots sold! During that time I had searched for my auctions about 5-6 times, and had never seen them listed. As Zancon had mentioned, at the time I listed them the market had been pretty flooded with lots of 10g. So if you can't see your lots, they may be in the "queue" to be listed eventually.
Thank you again for your help, Zancon!
