Just picked up a 2013 1oz Koala with Chinese Privy for my collection for an absolute bargain. Apparently only has a mintage of 10,392 but not sure how hard these are to find normally. They are selling on eBay for $650.
they were selling for $200-$400 a couple of years ago f I remember correctly. Looks like some have sold recently for under $100 which is slightly more reasonable, but privies are quite niche so volatility is expected I guess
