I agree with others on this thread. The biggest benefit of the Kilo is the lower premium (if you buy from the right dealer). Many times the premium can be about 1.50 over spot...which is a steal in my opinion. Many times the 10 oz has a higher premium, BUT maybe you capture that premium back over the long-term. My humble opinion is that the Kilos will do better once the declared mintage is made, I believe in 2019. Not sure if that is the case with the Koalas, but it is with the Lunars. All the best.
