Here's the thing. I have a reason to stack and I have a well thought out set of policies for stacking which I think are important given that I am comparatively new to this. Here is my methodology: I stack semi-numismatics. Whilst the appeal of a stack of shiny bars has a certain appeal, you are forever limited to the spot price where semi-numismatics guarantees the spot and has the potential for collectability. So I have a lot of goats and kookas in all sizes (remember I am new to this). I also bought crocs, WTE, various sharks and a bunch of those Privateers because I thought they might pay on their coolness. I have one or two opportunity buys as well but so far I have stuck to the game plan. I have resisted buying backwards and getting earlier kooks and lunars and have been waiting for monkeys so I can double the stack (they are just awful). The 9999 Kangas will probably go in as well but all in all I am determined to suppress the mad collector that lives in me and just stack on the principles I have outlined. But there is a collector in me. So I thought that I would create a little collection that didn't cost a lot of money and would satisfy the need to hunt and gather while I wait for Monkeys. I thought Australian Threepences might be a low cost little sideline so I started gathering them and learning on the way. After a couple of weeks, I am now a Threepence expert and have most of the basics set in UNC or EF+ and find myself being drawn to Florins, Sixpences etc. It's like a drug. I can't stop myself. I now have a 1937 UNC Crown and some Nazi silver. It's all silver of course as it adds to the stack but there is something seriously wrong with me. I can't control myself. I NEED a 1922/21 overstrike more than I need oxygen. I bought a 1936 5 Reichsmark coin because I am insane and it was 90% silver but I could have bought two Kangas for that...or food. What is wrong with me? Does anyone else do this?
