If it’s just sitting in your office and you don’t have many visitors, or none at all, then there’s no problem having a 1kg gold bar on display.
I have a Krugerrand sparkling in a stand that constantly reminds me of the day I could afford to buy my first gold coin with my own hard-earned money. It’s a great source of motivation.
Maybe I should swap my Krugerrand for a shiny 1kg gold bar instead… 😀
