I have seen a lot of whining against the Perth Mint on internet forums, but I personally love the quality and creativity in the kooks and lunars. I also love all the kangaroo carded coins issued by the Royal Australian Mint. I collect 1 and 2 ounce kooks, and any kind of kangaroo. They are all called "semi-numismatic" although I can't see why they are somehow less collectible than American coins. I am glad some mints bother to change the design on their coins every year. Will I see a return on investment? The 2-ounce kooks have gone up from $60-75 in 2012 to around $125 today on ebay.
