OK thanks for the correction as I was not aware of that. At the moment I am only buying silver.That, in my understanding is not necessarily correct. While there is no state sales tax on gold, silver or platinum, there is a Texas state sales tax on palladium and copper (source - paragraph 2). Palladium is definitely a precious metal, it is at a bid price of $2,162.00 as I write. In fact it is another one I am truly sad I never purchased a few years back. Whenever there are high world tensions, especially when Russia is pissed off at the world, Palladium & Rhodium will be way up. They are mined only in a few areas - Russia being one of them.
