Hi all. I've had an opportunity to nab a nice platinum 1/2 oz koala coin at a reasonable price but I'm not sure if there are any pitfalls when it comes to the other white metal. I assume that things are less liquid when it comes to platinum and palladium (less people interested / fewer metals buyers take it)? Apart from that I take it things are roughly the same when it comes to premiums and costs involved with owning physical? Any general differences worth mentioning you've noticed between holding gold and silver vs platinum (or palladium/rhodium) would be appreciated.
