The only one I've been able to find just trades regular acorns. I'll have to try to get more to trade in case he has different tiers of trade, other than that just keep looking around.

Yep, it's like I guessed. After you trade him 15 regular ones, he then trades for the gold ones. I just didn't have 15 regular ones till I got my farm up and running.
